Wirecutter senior staff writer Melanie Harga Notebook Medan Pinola has written about technology and home-office topics for more than a dozen years for sites such as Lifehacker, PCWorld, Popular Mechanics, and Laptop Magazine. For over five years, she has tested and reviewed gear for Wirecutter, including home-office essentials such as webcams, USB microphones, and office chairs. She’s a die-hard stationery fan who uses notebooks daily for work and personal projects; it’s probably telling that almost everyone close to her has gifted her a notebook at one point or another.

During our preliminary notebook research, we consulted with and relied upon the work of experienced bloggers who review pens, pencils, and stationery. These people care far more about the performance of paper against all sorts of writing implements than most people, and they also have a wide range of papers to compare notebooks with. In particular, we traded emails with three bloggers to inquire after their favorite notebooks: Brad Dowdy, The Pen Addict, is a co-founder of Nock Co., which makes notebooks and stationery bags; Elizabeth Newberry of No Pen Intended has written hundreds of reviews of pens and notebooks and particularly appreciates paper that can stand up to a fountain pen; and Ian Hedley of Pens! Paper! Pencils! is a professional artist who also runs the pen blog search engine Pennaquod. We also interviewed (via email) a representative from the online stationery store JetPens and several notebook enthusiasts who contribute to Reddit’s r/notebooks subreddit.

A medium softcover notebook with silky pages: Apica Premium CD Notebook

Get this if: You want a softcover notebook that is the size of a trade paperback book and has super-smooth paper your pen will glide over. If you write with a fountain pen or rollerball, you’ll probably appreciate how well this notebook’s paper shows off ink colors.

Why it’s great: Four out of five Wirecutter panelists chose the Apica Premium CD Notebook as their top or second-favorite notebook pick, saying the feel of the paper was the “best out of the bunch” and “silky yet not ‘plastic-y’ like some others.” The paper stood up well to a range of writing instruments—even demanding fountain pen ink—with little feathering and minimal ghosting.

We also liked the paper’s off-white, eggshell color—neither too bright nor too yellow—and the simple, well-spaced, light gray line ruling. The cardstock cover is sturdy, and the stitched binding is high quality, allowing the notebook to lie flat nicely. All in all, this is a great all-purpose notebook with thick paper that feels luxurious to the touch.

The Apica Premium CD Notebook’s paper has a pleasant off-white tone, and ink looks great on it. Photo: Michael Hession

Flaws but not dealbreakers: The Apica’s super-smooth paper isn’t for everyone, especially those who are expecting a traditional paper feel as you get with typical composition notebooks. It feels more like the slick pages of The New York Times’s Sunday Magazine than the tougher paper that makes up the rest of the newspaper. Or, for another analogy, like sateen bed sheets lawan jersey knit sheets.

The notebook’s old-fashioned cover design might come across as kitschy to some, but you could always customize it with a cover, which would improve the notebook’s durability.

Also, it doesn’t come with a ribbon laman marker, and although it has a small index on the first halaman, the pages aren’t numbered. We don’t think those features are essential for most people, but if they matter to you, consider the Leuchtturm1917 in softcover.

Size: A5 (lima.8 by 8.tiga inches), 192 pagesRuling options: lined, graph, blank

A medium softcover notebook with more texture: Midori MD Notebook

Photo: Michael HessionAlso great

Get this if: You want a simple, medium-size notebook with paper that’s easy on the eyes and offers tactile feedback—the rougher paper slows your writing down and makes you pay more attention to it, in contrast to slicker paper that your pen would glide across. The Midori MD Notebook strikes a delicate balance between smoothness and “toothiness,” so if you like feeling a bit more friction than you get from the more coated or vellum papers of other notebooks, this might be the one for you.

Why it’s great: The Midori MD Notebook is simplicity at its best, with a plain cream-colored cardstock cover and matte pages with light blue ruling. Three out of five testers ranked this notebook in their top three, saying they loved the pleasant tone of the paper and the notebook’s minimalist aesthetic, which makes writing and journaling as distraction-free as possible. It takes all sorts of ink but handles pencil especially well because of the paper’s slight tooth; the blank or graph versions of the Midori MD would be great for doodling or sketching. There is some ghosting or show-through on the other side of the page, but we didn’t find it intrusive.

Construction-wise, the quality of the stitching is terrific, allowing the notebook to lie flat. (Compared with other notebooks of this size, including the Apica Premium CD, the Midori MD is bound in more, smaller sections, called signatures—16 signatures versus a more common eight or 12—which makes it sturdier and helps it lie flat more easily.) Unlike many other soft notebooks, this one has a ribbon bookmark—a silky green one that nicely complements the cream Grosir Notebook Medan pages.

Flaws but not dealbreakers: Our main complaint against this otherwise lovely notebook is the dark horizontal line that runs across the middle of all the pages. While some people might use this line to divide their notes, we found it distracting and unnecessary.

This is also a notebook you might want to get a cover for, because although the cardstock feels sturdy, it’s not as rugged or as thick as other notebooks’ covers. (It comes with a thin plastic cover, but we found that more intrusive than useful.) Clear, paper, and leather covers are available at JetPens.

Although most of our testers didn’t experience a lot of smudging with most writing utensils, our left-handed tester found that this notebook’s paper smudged significantly more with a gel pen than others did.

A hardcover notebook for journaling or rencana: Leuchtturm1917 Hardcover Notebook

Photo: Michael HessionOur pick

Get this if: You want a medium-size hardcover notebook that helps you organize and keep track of your thoughts and ideas. All of the tiny details, such as the index pages and labels for archiving, make this notebook gift-worthy, too.

Why it’s great: The Leuchtturm1917 Hardcover Notebook was the favorite notebook of three of our testers, and they listed many reasons for that. Most of all, the cream-colored paper is exquisite, with a powdery, toothy feel unlike that of any of the other notebooks we tested or have used in the past. (In a pile of more than 20 notebooks, this is the one I could most readily pick out if blindfolded.) The paper took well to pencil, ballpoint, rollerball, gel pen, and fountain pens, with very little smudging and no bleeding. Most of our testers said it just felt good to write on.

We love the firm cover and the ample laman count, as well as all the extras this notebook offers: two thick ribbon bookmarks, labels for the spine and title page, page numbers, index pages, and a sturdy back pocket.

A Quick Guide to Designing CNC Machined Parts

Optimize your designs to avoid unnecessary machining features, limit part complexity, help reduce CNC machining costs and time, and create machined parts faster and more efficiently.As large an internal radius as possible

Any internal cut will generate a fillet that is half the diameter of the tool used. Milling with smaller tools takes a long time and we recommend that the radius should be greater than 1/3 of the depth of machining. The best bet is to relieve internal corners or allow for as large an internal radius as possible on mating part designs and use the same radius on all inside edges so that the same tool can be used throughout the CNC machining processes.Avoid overly deep cavities, grooves and holes

Tahapan Dan Cara Memulai Bisnis Event Organizer

Usaha Event Organizer atau sering dianggap menggunakan EO (baca: i-o) Jasa EO adalah galat satu jenis Outbound Training usaha jasa yg sanggup dilakukan setiap orang tanpa mengenal batasan usia ataupun peJasa Event Organizer kerjaan, selama anda dapat menyusun & merancang konsep program dengan rinci & matang.

Cakupan program atau event yg sanggup dilakukan oleh Event Organizer pun sangat luas & majemuk, mulai Pembicara Seminar berdasarkan acara tujuh belasan, ulang tahun, pernikahan, sampai kepada konser ataupun pameran skala internasional.

Banyak sekali yg mencoba berbisnis sebagai Event Organizer, mulai menurut skala yg kecil, individu, hingga ke skala akbar & menciptakan perusahaan sendiri yg umumnya sudah mempunyai pemodal dan program rutin serta tim sendiri.

Rentang usia para pelaku Event Organizer ini pun pula majemuk, mulai dari tim kepanitiaan anak Sekolah Menengah Atas, kuliah, bunda tempat tinggaltangga, karyawan, sampai wiraswasta yang memang berfokus kepada kegiatan tadi.

Jika anda termasuk keliru satu yang tertarik memulai usaha Event Organizer namun masih resah bagaimana memulainya, dalam artikel ini kami akan bahas secara mendalam tentang bagaimana melakukan hal tadi secara termin demi tahap.

Tetapi bila anda lebih tertarik dengan bisnis online, silahkan baca beberapa artikel yang kami buat terkait hal tadi, misalnya cara sebagai reseller online shop, lalu cara sukses usia muda melalui bisnis online, tips usaha sukses bagi pemula, dan lain sebagainya.Apa Lingkup Pekerjaan Event Organizer ?

SeIn House Training belum mengetahui langkah-langkah dan cara memulai bisnis Event Organizer, terdapat baiknya anda tahu terlebih dahulu seluk beluk serta lingkup pekerjaan menurut mereka yg menjalani bisnis tersebut.

Secara umum, menjadi Event Organizer berarti anda adalah yang bertanggung jawab pada mengorganisir dan mengeksekusi jalannya suatu kegiatan, entah itu kegiatan yang anda rancang sendiri konsepnya, ataupun kegiatan yang ditugaskan kepada anda sang orang lain.

Dalam lingkup yg lebih khusus, sebagai Event Organizer itu berarti anda bertanggung jawab atas seluruh hal di belakang layar, yg beberapa diantaranya adalah sebagai berikut:Menyusun & mengalokasikan anggaran untuk setiap hal yg dibutuhkan sang suatu Event,Menentukan dan memastikan ketersediaan perlengkapan yang dibutuhkan,Memastikan lokasi aktivitas dapat dan layak dipakai,Memastikan anda mempekerjakan SDM yg cukup,Memastikan akomodasi, transportasi, & konsumsi dari panitia dan pengunjung terpenuhi,& lain sebagainya.

Tentunya lingkup pekerjaan nantinya akan disesuaikan menggunakan jenis event yg anda selenggarakan, & mungkin tidak seluruh hal di atas akan anda lakukan, atau sangat mungkin akan jauh lebih kompleks dibandingkan daftar di atas tersebut.Skill yg diharapkan Event Organizer

Selanjutnya pada menjalankan usaha Event Organizer, anda sebaiknya pula harus memiliki skill alias ketrampilan pada beberapa hal supaya acara dapat berjalan menggunakan lancar, atau minimal mengurangi risiko kegagalan.

Misalnya buat menyusun aturan, sangat disarankan buat anda menguasai Microsoft Excel ataupun aplikasi sejenisnya sebagai akibatnya anda akan lebih mudah memantau serta mempelajari ulang anggaran yg sudah anda susun buat lalu direvisi.

Akan lebih membantu juga bila anda merupakan seseorang yg teliti,serta piawai dalam melihat hal-hal yang detail, dan tentunya akan sangat membantu apabila anda telah memiliki pengalaman sebelumnya dalam menyelenggarakan suatu event.

Pengelolaan keuangan yg baik serta ketrampilan pada negosiasi juga sangat dibutuhkan, terutama apabila event yang anda selenggarakan membutuhkan sponsorship yang mana anda wajibmengajukan proposal pada para calon sponsor yg sekiranya tertarik berkontribusi buat aktivitas yg akan anda lakukan tadi.Langkah Menjadi Event Organizer

Setelah mengetahui lingkup pekerjaan & ketrampilan yg diharapkan, kemudian bagaimana usahakan cara memulai bisnis Event Organizer yang sempurna dan nir salahlangkah ?

Berikut ini akan kami berikan penjelasannya secara bertahap, yang sanggup anda coba praktekkan bila anda ingin mulai menggeluti bisnis Event Organizer ini dan menjadikannya sebagai usaha primer anda kedepannya.1. Menambah pengalaman (bila anda belum memilikinya)

Langkah pertama pada cara memulai bisnis event organizer merupakan dengan menambah pengalaman anda, terutama jika anda belum pernah menangani suatu event sebelumnya.

Anda bisa bergabung dengan kepanitiaan program di lebih kurang rumah, sekolah, atau kampus anda, atau bergabung dengan Event Organizer yang telah berdiri lebih dahulu, supaya anda mampu lebih memahami bagaimana cara kerja dan apa saja yang perlu dikerjakan.

Biasanya suatu kepanitian akan terbagi ke pada beberapa gerombolanatau seksi, misalnya seksi program, perlengkapan, publikasi, keamanan, atau konsumsi, & usahakan anda mencoba bekerja di seluruh seksi yang ada agar pemahaman anda mengenai pekerjaan di pada seksi tersebut semakin bertambah.dua. Kumpulkan tim

Setelah anda merasa cukup berpengalaman, tahapan selanjutnya dalam cara memulai usaha Event Organizer merupakan anda mampu mulai menciptakan tim yang terdiri menurut orang-orang yg anda percaya bisa membantu anda pada menjalankan bisnis Event Organizer tersebut.

Pada tahapan ini sebenarnya sangat belum pasti, lantaran mampu saja anda beranjak sendirian atau berdua, dan residu pekerjaan lainnya mampu anda limpahkan pada pihak ketiga alias vendor yg telah anda percaya kualitasnya.

Tim yang kami maksud di sini bukanlah orang-orang yg akan bertugas menjadi eksekutor pada lapangan, melainkan terdiri menurut individu yg mampu membantu anda merancang konsep, menyusun aturan dan proposal, dan tugas-tugas primer lainnya.tiga. Jalin kerjasama menggunakan vendor

Seperti telah kami singgung sedikit dalam poin sebelumnya di atas, anda pula harus menjalin kerjasama dengan vendor-vendor yg mampu anda percaya dan sudah terbukti kualitas pekerjaannya.

Beberapa jenis vendor yg krusial dan umumnya dibutuhkan pada beberapa jenis event misalnya adalah vendor buat panggung, sound system, pencahayaan (lighting), dekorasi, & penyediaan indera-alat seperti genset, AC portabel, projektor beserta layar, & lain sebagainya.4. Promosikan ke dalam lingkaran pertemanan dan keluarga

Untuk mulai mempromosikan usaha anda, mulailah berdasarkan lingkungan terdekat terlebih dahulu contohnya sahabat-teman anda atau anggota famili, baik keluarga inti ataupun keluarga jauh.

Hal ini dikarenakan pengelolaan event ini sanggup dilakukan oleh siapa saja, dan karena itu anda sahih-sahih membutuhkan dapat dipercaya apabila anda ingin dipercaya mengerjakan event skala akbar, sebagai akibatnya memulai menurut orang-orang terdekat akan menjadikan anda lebih mudah dipercaya dan secara perlahan menambah pengalaman anda.lima. Mulai dari event skala kecil

Tahapan selanjutnya dalam cara memulai usaha event organizer adalah dengan memulai menurut mengerjakan event skala miniterlebih dahulu sebelum mulai mengerjakan event yg skalanya lebih besar .

Misalnya membantu menyelenggarakan program tujuh belasan di perumahan anda, turnamen game atau olahraga mini-kecilan, program pernikahan sahabat atau kerabat anda, mengadakan kegiatan wisata buat rombongan atau aktivitas outbound, & lain sebagainya yg skalanya nir terlalu besardan membutuhkan modal yg besar .6. Permodalan

Selanjutnya anda pula perlu memikirkan mengenai kapital yg diharapkan buat mendanai suatu event atau kegiatan, yg jua merupakan keliru satu hal penting di pada tahapan & cara memulai usaha event organizer.

Ada beberapa metode pemodalan yang mampu anda pertimbangkan dalam waktu akan menjalankan suatu event, yaitu kapital sendiri, donasi atau sumbangan berdasarkan orang lain, mencari sponsor yg mau mendanai aktivitas tadi, atau campuran berdasarkan ketiganya.

Untuk jenis event tertentu contohnya turnamen game, kontes musik, atau turnamen olah raga, pendapatan pula sanggup anda dapatkan menurut uang pendaftaranyang anda kenakan kepada para partisipan, atau berdasarkan penjualan tiket masuk, meskipun usahakan anda tidak bergantung kepada hal ini.

Mengapa uang registrasi atau tiket masuk bukan merupakan salahsatu alternatif pendanaan yang baik buat event ? Lantaran risikonya terlalu tinggi & sebagus apapu kenaikan pangkatanda permanen nir mampu diperkirakan berapa pendapatan yang akan anda terima melalui kedua hal tersebut.

Sebaiknya pendapatan menurut uang registrasi ataupun tiket masuk anda kategorikan sebagai laba, atau sebagai “uang jaga-jaga” apabila ternyata dalam saat pelaksanaan kegiatan terdapat biaya -biayatak terduga yg ada.

Untuk kapital sendiri, yg kami maksud pada sini nir serta merta uang yang dikeluarkan berdasarkan kocek anda saja, namun apabila jasa Event Organizer anda ditunjuk menjadi pelaksana aktivitas oleh suatu organisasi, institusi, atau perusahaan, maka dana yg mereka keluarkan buat membayar anda jua termasuk ke dalam kategori ini.

Electrical Discharge Machining ( Edm ) Design Consideration Process Capabilities

Electrical Discharge Machining ( EDM ) Design Considerations Process Capabilities

Manufacturing Knowledge MenuEDM Manufacturing ServicesEDM Manufacturing Equipment

Electrical Discharge Machining, EDM is one of the most accurate manufacturing processes available for creating complex or simple shapes and geometries within parts and assemblies. EDM works by eroding material in the path of electrical discharges that form an arc between an electrode tool and the work piece.  EDM manufacturing is quite affordable and a very desirable manufacturing process when low counts or high accuracy is required.  Turn around time can be fast and depends on manufacturer back log.

The EDM system consists of a shaped tool or wire electrode, and the part. The part is connected to a power supply. Sometimes to create a potential difference between the work piece and tool, the work piece is immersed in a dielectric (electrically non conducting fluid which is circulated to flush away debris.

The cutting pattern is usually CNC controlled.  Many EDM machine electrodes can rotate about two-three axis allowing for cutting of internal cavities. This makes EDM a highly capable manufacturing process.

EDM comes in two basic types: wire and probe (die sinker). Wire EDM is used Jasa Machining primarily for shapes cut shapes through a selected part or assembly. With a wire EDM machine, if a cutout needs to be created, an initial hole must first be drilled in the material, then the wire can be fed through the hole to complete the machining. Sinker (die sinking EDM’s are generally used for complex geometries where the EDM machine uses a machined graphite or copper electrode to erode the desired shape into the part or assembly. Sinker EDM can cut a hole into the part without having a hole pre-drilled for the electrode.

EDM Power System. The discharge energy during EDM is provided by a direct current pulse power generator. The EDM power system can be classified into RC, LC, RLC, and transistorized types. The transistorized EDM power systems provide square waveform pulses with the pulse on-time usually ranging from 1 to 2000 msec, peak Jasa Machining Medan voltage ranging from 40 to 400V, and peak discharge current ranging from 0.lima to 500 A. With the RC, LC, or RLC type power system, the discharge energy comes from a capacitor that is connected in parallel with the machining gap. As a result of the low impedance of plasma channel, the discharge duration is very short (less than lima msec), and the discharge current is very high, up to 1000 A. The peak voltage is in the same range of transistorized power systems.

The transistorized power systems are usually used in die-sinking EDM operations because of their lower tool wear. Capacitive power systems are used for small hole drilling, machining of advanced materials, and micro-EDM because of higher material removal rate and better process stability. WEDM power generator usually is a transistor-controlled capacitive power system that reduces the wire rupture risk. In this power system, the discharge frequency can be controlled by adjusting the on-time and off time of the transistors that control the charging pulse for the capacitor connected in parallel with the machining gap.

Key EDM System Components: The machining gap between tool and work piece during EDM must be submerged in an electrically nonconductive dielectric fluid. In die-sinking EDM, kerosene is often used as a dielectric fluid because it provides lower tool wear, higher accuracy, and better surface quality. Deionized water is always used as a dielectric fluid in WEDM to provide a larger gap size and lower wire temperature in order to reduce the wire rupture risk. This fluid also serves to flush debris from the gap and thus helps maintain surface quality.

Copper and graphite are commonly used as die-sinking EDM tool materials because of the high electrical conductivity and high melting temperature and the ease of being fabricated into complicated shapes. The wire electrode for WEDM is usually made of copper, brass, or molybdenum in a diameter ranging from 0.01 to 0.5 mm. Stratified copper wire coated with zinc brass with diameter of 0.25 mm is often used.

In the traditional die-sinking EDM process, the tool is fabricated into a required shape and mounted on a ram that moves vertically. The spark discharges can only occur under a particular gap size that determines the strength of electric field to break down the dielectric. A servo control mechanism is equipped to monitor the gap voltage and to drive the machine ram moving up or down to obtain a dischargeable gap size and maintain continuous sparking. Because the average gap voltage is approximately proportional to the gap size, the servo system controls the ram position to keep the average gap voltage as close as possible to a preset voltage, known as the servo reference voltage.

In a WED machine, the wire electrode is held vertically by two wire guides located separately above and beneath the work piece with the wire traveling longitudinally during machining. The work piece is usually mounted on an x-y table. The trajectory of the relative movement between wire and work piece in the x-y coordinate space is controlled by a CNC servo system according to a preprogrammed cutting passage. The CNC servo system also adjusts the machining gap size in real time, similar to the die sinking EDM operation. The dielectric fluid is sprayed from above and beneath the work piece into the machining gap with two nozzles.

The power generators in WED machines usually are transistor-controlled RC or RLC systems that provide higher machining rate and larger gap size to reduce wire rupture risks. In some WED machines, the machining gap is submerged into the dielectric fluid to avoid wire vibration to obtain a better accuracy. The upper wire guide is also controlled by the CNC system in many WED machines. During machining, the upper wire guide and the x-y table simultaneously move along their own preprogrammed trajectories to produce a taper and/or twist surface on the work piece.

Advantages of EDM :Complex shapes that would otherwise be difficult to produce with conventional cutting tools Extremely hard material to very close tolerances Very small work pieces where conventional machining tools may damage the part from excess cutting tool pressure. There is no direct contact between tool and work piece. Therefore delicate sections and weak materials can be machined without any distortion.

Disadvantages of EDM :Relatively s low rate of material removal. Additional lead time and cost used for creating electrodes for ram/sinker EDM. Reproducing sharp corners on the workpiece is difficult due to electrode wear. Electrical power consumption is high. Material must be electrically conductive

Mechanical Design Considerations:Relax the surface-finish for the part, if feasible. This allows the manufacturer to produce the part with fewer passes, at a higher current level and a higher metal-removal rate.Design or prepare the part such that the amount of stock removed by EDM is relatively small. Use traditional machining techniques to remove the bulk of the stock with the finishing operations performed by EDM. This significantly reduces the amount of time and cost for each part.The EDM manufacturer should consider fixtures such that several parts can be stacked and machined simultaneously or a single part can have several EDM operations performed simultaneously.When existing holes are to be enlarged or reshaped by EDM, through holes are preferred to blind holes as they permit easier flow of dielectric fluid past the area being machinedThere will be some degree of materials exchange between the EDM wire / probe and the base material. Specify a cleaning procedure is galvanic corrosion is a concern.The minimum internal corner radius of cut feature will dictate the maximum wire diameter that can be used. Obviously, the wire diameter needs to be at less than double the minimum inside corner radius. However, one also has to account for the amount of final over cut, plus a small amount of “maneuvering” room, so that the CNC can generate the corner. This is analogous to CNC contour milling, in which accurate internal corner radii are generated by machine motion, rather than just plunging an end mill into a corner and accepting the result. Usually, “the bigger, the better” for wire diameters up to .010″. It is important to note that the new Jasa Machining Medan “twin wire” machines can employ a different strategy for these conditions, however, most of us do not have this luxury. Recommendations for small diameter wires include:High Tensile Brass wire for .006″ diameterSteel Core wire from .002″ to .004″ diameter Moly wire from .002″ to .004″ Tungsten wire from .0008″ to .002″
