A new look for gear milling – Iscar

Technology and its products are often causative: A technology might be applied to develop more effective and intelligent products, which in turn can play an important role in advancing that technology.

This interrelationship may be observed in metalworking. Over the last few years, leading-edge technology has resulted in multitasking machine tools and machining centers with impressive working possibilities. At the same time, this progress in machine tool engineering is significantly changing metal cutting technology.

The advanced multifunctional machine tools increasingly widen the range of machining operations that can be performed. Technological processes developed for these machines are oriented to maximise machining operation for one-setup manufacturing, creating a new source for more accurate and productive manufacturing. Milling gears and splines is one of the operations suitable for performing on the new machines.


Traditionally, gear (and spline) making is a complicated process that involves milling, chamfering, grinding and other operations. With batch manufacturing, the majority is made on specific machines like gear hobbing, gear shaving, gear grinding and so on. Developments in technology have changed the limits of hardness for cutting and considerably increased operational accuracy. This in turn has reduced abrasive machining in gear making while decreasing rough cutting. The modern multifunctional machines, which meet the requirements of one-set-up manufacturing, have proved to be perfect for various gear making operations.

These new machines require appropriate tooling and cutting tools manufacturers should prepare their response accordingly, which is why producers of general purpose rotating cutting tools are reconsidering the role of gear-milling cutters in their programme for standard product lines.

Iscar, one of the leaders in the cutting tool industry, is embodying this trend with a three-point programme for form gear making tools:

• Milling cutters carrying indexable inserts
• Milling cutters with replaceable cutting heads based on the T-Slot concept
• Milling cutters with replaceable Multi-Master cutting heads

ModuGear, the family of indexable gear milling cutters reflects a conventional design approach, comprising disk-type tools with tangentially clamped LNET inserts. The tangential clamping principle provides an extremely rigid and durable cutter structure that results in stable and precise enough machining tooth or spline profiles. Its principal application is producing involute gears of relatively low accuracy and rough gear-milling operations that feature a 1mm to 1.75mm gear module range.


The cutters with replaceable heads have two significant advantages compared with gear milling tools carrying indexable inserts. They offer better precision and allow the design of gear-milling cutters that are small in diameter but feature quite a large number of teeth. The replaceable heads are mounted in bodies (shanks), which are standard-line products suitable not only for the gear-milling heads but also for other types of head (for milling slots and grooves, for example). This enables customers to increase operating efficiency of the versatile shanks and to reduce tool stock, providing added value.

The replaceable solid carbide heads of the T-Gear SD D32-M…-SP15 family are mounted in standard T-Slot SD-SP15 cylindrical shanks and transform the latter into 32mm diameter gear milling cutters. The precise profile of the cutters’ teeth and the accurate and reliable SP-connection between the shank and the head define its range of use: Milling involute gears featuring a 1mm to 2mm module.

Both types of milling cutters (those with indexable inserts and those with replaceable heads) meet the requirements of standard DIN 3972, basic profile II.

There are two types of Multi-Master spline and gear making solid carbide heads. The first type is represented by the MM SS heads that were specially designed for milling involute spline shafts, specified by DIN 5480 and ANSI B92.1 standards. These heads are intended for 1mm, 1.25mm, 1.5mm and 3mm module (DIN 5480) and 8mm, 10mm, 12mm and 24mm diametral pitch (ANSI B92.1).

The heads of the second type, MM SG, are used in milling spur gears in accordance with DIN 3972 (module 1mm to 1.75mm) and ANSI B6.1 (diametral pitch 15mm to 24mm) standards.

The main application field for Multi-Master heads is the efficient production of small to medium batches of spline and spur gears in various industrial branches.

The world of gears is very rich and multiform, embracing a wide variety of external and internal gears like spur, helical, bevel, hypoid, and more. Manufacturing these gears encompasses an entire, dynamic industrial sector with its own methods, equipment and tooling. The introduction of multitasking machines in gear milling as a serious alternative to a dedicated machine represents a new challenge to this sector and producers of commonly used cutting tools should be ready for this significant change. Iscar meets this challenge while maintaining the requisite high standards demanded by end users.


5 Android apps you shouldn’t miss this week! – Android Apps Weekly

Android Apps Weekly featured image

Welcome to the 210th edition of Android Apps Weekly! Here are the big headlines from the last week:

  • Pokemon Go might get some new features soon. The developers acknowledged that playing games on AR is rough. You spend all your time looking at your phone. The new feature could include audio cues. That way you know when Pokemon are around, where Poke Stops are, etc. There is talk that it might be a hallmark feature in the follow-up game to Pokemon Go.
  • The classic infinite runner Into the Dead is getting a sequel. Into the Dead 2 is launching to the Play Store on October 13th. The new game will contain 60 levels across seven chapters. Most of the mechanical elements should be similar to the first game. It’s available for pre-registering on Google Play right now.
  • Chainfire released a new website this week for root users. The site is a spot for devs, root users, etc to find stock boot and recovery images. It’s mostly stuff for Google Pixel and Samsung phones. It should expand over time to include more devices. It should also make finding such files easier for beginners and advanced users alike.
  • Google Assistant is getting some new features. At least we think so. During an APK tear down, it revealed some new information. Included is an Active Edge feature that may be similar to HTC’s phone squeezing feature. There are also hints of features like customizable short commands for Assistant. These may or may not be real, but it would be cool if they were.
  • Minecraft’s long awaited Better Together update is out. The game allows for cross-platform play between console, PC, and mobile. Namely, it works on Xbox, Windows 10, VR, and mobile devices. In addition, they added a bunch of other items to the game. They also announced that the game is coming to the Nintendo Switch.

Codex of Victory is a new strategy game. The game is a hybrid of a classic strategy game and a kingdom builder. You build bases, upgrade units, and conduct combat against the enemy. It features a story-driven, single player campaign mode. The developers also boast 20 hours of single player campaign, over 25 units to build and upgrade, and more. The levels are also randomly generated. That means no two playthroughs are alike. It runs $4.49, but has no in-app purchases or advertising.

Reverse Dictionary is a simple dictionary app. It helps you figure out a word that you can’t think of. You simply type letters of the word, a phrase describing it, or synonyms of the word. The app then attempts to tell you what word you were looking for. It features a light, simple design. The app also does work pretty well. Otherwise, it’s a simple little app that shouldn’t take up too much space on your phone. It’s completely free with no ads and no in-app purchases.

High-Octane Filmmaking – with Top Gear director Avi Cohen – ON THE GO – Episode 65

In this episode of cinema5D ON THE GO, we meet high-octane automotive director Avi Cohen, and discuss his work on the famous car show Top Gear.

Avi Cohen

With a portfolio of work focusing mostly on automobiles, we knew that fast cars were nothing new to Avi Cohen — we were sure he was going to feel right at home in our ON THE GO Mustang.

Avi’s is the kind of life story many out there would envy. With a late start in filmmaking in his mid-20’s in San Francisco while taking a few film classes in community college, he experienced an instant connection and understanding of the visual language.

After moving to Los Angeles, Avi Cohen picked up a Sony EX1 to shoot content that he found interesting in order to put together a reel. Not having the usual network of actors, directors and other contacts that film school offers, Avi’s subjects consisted mostly of skaters, dirt bike riders and snails.

However, it was during this experimental stage that he honed his skills in shooting cars, and developed his own vision which eventually landed him a role as a director on Top Gear. Check out the trailer for the upcoming season below!

Avi Cohen also tells us about the work dynamics of shooting Top Gear, his interaction with the writers, and how it all comes together.

Stay tuned for the second half of our chat with director Avi Cohen! In the meantime, head over to Avi’s website to see more of his work.

Performers/Creatives reviews – Irvine Welsh’s two plays are exercises in tedium

Embarrassingly limp: George Russo and Perry Benson in Performers.

Not so much theatre shows as exercises in tedium, these new pieces from Trainspotting author Irvine Welsh would never have seen the light of day if they didn’t have his name attached. An audience expecting the skanky wit and vim of Trainspotting will be disappointed by this duo of tired and clumsy plays.

Performers, written with Dean Cavanagh, is potentially the more interesting of the two. Apparently, when making the 1970 movie Performance, which starred Mick Jagger and James Fox, directors Nicolas Roeg and Donald Cammell wanted to hire real villains to play the gangsters. Their quest for authenticity sees low-life criminals Alf (Perry Benson) and Bert (George Russo) turning up at the production offices. But with slack direction from Nick Moran, it has all the tension of a used teabag. The comic tour de force that is supposed to ensue when a pretentious young assistant director persuades Alf to take off his clothes is embarrassingly limp.

Set in 1969, it would have looked dated and if it had actually been written that year, and – in their own quest for authenticity – Welsh and Cavanagh appear to have copied out a cockney rhyming slang dictionary lock, stock and barrel.

If Performers aims for comic grittiness and misses by a mile, Creatives is all bland, slick shininess; straight out of the Fame mould. It’s a musical, written with Don de Grazia, about a group of would-be songwriters attending a Chicago course run by former punk Paul, whose career has nosedived and whose personal life is complicated.

The students are all stereotypes, ranging from moody goth girl to (bizarrely) a redneck Trump supporter, and the entire thing starts to resemble an audition for the X Factor but with less convincing back stories, until a violent plot twist pushes it into outright melodrama.

The US cast are game, and Laurence Mark Wythe’s music and lyrics cry out for a better vehicle than this cliched attempt to explore the price of creativity and the pressures to sell out for a quick buck. One imagines that is exactly what Welsh has done with these abysmal efforts.

 Performers is at the Assembly Rooms until 27 August. Box office: 0131-623 3030. Creatives is at the Pleasance Courtyard until 28 August. Box office: 0131-556 6550.
