Gear Tool Sharpening Optimization

The sharpening of gear tools, including hobs, milling cutters, and shaper cutters, impacts the productivity and cost-per-unit for all gear manufacturers. Learn specific areas to improve the efficiency of a gear tool sharpening operation. This includes transportation of workpieces, inspection, preparation, machining, and idle time. Supervisors and operators can comfortably roll-out these actions for measurable and lasting productivity improvements. Article Courtesy of Helios Gear Products

1 New Concepts in CNC Gear Shaping (July/August 1995)

In today's economy, when purchasing a new state-of-the-art gear shaper means a significant capital investment, common sense alone dictates that you develop strategies to get the most for your money. One of the best ways to do this is to take advantage of the sophistication of the machine to make it more than just a single-purpose tool.

2 Gear Shaping Machines CNC Developement (November/December 1985)

Up until approximately 1968-69, pinion cutter-type gear shaping machines had changed very little since their conception in the early 1900's.

3 Avoiding Interference In Shaper-Cut Gears (January/February 1996)

In the process of developing gear trains, it occasionally occurs that the tip of one gear will drag in the fillet of the mating gear. The first reaction may be to assume that the outside diameter of the gear is too large. This article is intended to show that although the gear dimensions follow AGMA guidelines, if the gear is cut with a shaper, the cutting process may not provide sufficient relief in the fillet area and be the cause of the interference.

4 Computer Aided Design for Gear Shaper Cutters (November/December 1987)

Computer programs have been developed to completely design spur and helical gear shaper cutters starting from the specifications of the gear to be cut and the type of gear shaper to be used. The programs generate the working drawing of the cutter and, through the use of a precision plotter, generate enlarge scaled layouts of the gear as produced by the cutter and any other layouts needed for its manufacture.

5 Design Implications for Shaper Cutters (July/August 1996)

A gear shaper cutter is actually a gear with relieved cutting edges and increased addendum for providing clearance in the root of the gear being cut. The maximum outside diameter of such a cutter is limited to the diameter at which the teeth become pointed. The minimum diameter occurs when the outside diameter of the cutter and the base circle are the same. Those theoretical extremes, coupled with the side clearance, which is normally 2 degrees for coarse pitch cutters an d1.5 degrees for cutters approximately 24-pitch and finer, will determine the theoretical face width of a cutter.

6 New Guideless CNC Shaper for Helical Gears (March/April 1998)

Product announcements so often trumpet minor, incremental advances with works like "revolutionary" and "unique" that even the best thesaurus can fail to offer a fresh alternative to alert the reader when something really innovative and important is introduced. In the case of Mitsubishi's new CNC gear shaper, the ST25CNC, both terms apply.

7 Determining the Shaper Cut Helical Gear Fillet Profile (September/October 2006)

This article describes a root fillet form calculating method for a helical gear generated with a shaper cutter.

8 Big Gears Better and Faster (January/February 2011)

Indexable carbide insert cutting tools for gears are nothing new. But big gears have recently become a very big business. The result is that there's been a renewed interest in carbide insert cutting tools.

9 Shaper Cutters-Design & Applications Part 1 (March/April 1990)

Gear shaping is one of the most popular production choices in gear manufacturing. While the gear shaping process is really the most versatile of all the gear manufacturing methods and can cut a wide variety of gears, certain types of gears can only be cut by this process. These are gears closely adjacent to shoulders; gears adjacent to other gears, such as on countershafts; internal gears, either open or blind ended; crown or face gears; herringbone gears of the solid configuration of with a small center groove; rack; parts with filled-in spaces or teeth, such as are used in some clutches.

10 Runout, Helix Accuracy and Shaper Cutters (June/July 2012)

Our experts discuss runout and helix accuracy, as well as the maximum number of teeth in a shaper cutter.

11 Shaper Cutters - Design & Application - Part 2 (May/June 1990)

Cutter Sharpening Cutter sharpening is very important both during manufacturing and subsequently in resharpening after dulling. Not only does this process affect cutter "over cutting edge" quality and the quality of the part cut, but it can also affect the manner in which chip flow takes place on the cutter face if the surface finished is too rough or rippled.

12 New Cutting Tool Developments in Gear Shaping Technology (January/February 1993)

The advent of CNC technology as applied to gear shaping machines has, in the last 10 years, led to an astonishing improvement in both productivity and quality. As is usual when developments such as this take place, the technology of the machine tool suddenly jumps ahead of that of the cutting tool, and the machine is then capable of producing faster than the cutting tool can withstand.

13 Innovative CNC Gear Shaping (January/February 1994)

The Shaping Process - A Quick Review of the Working Principle. In the shaping process, cutter and workpiece represent a drive with parallel axes rotating in mesh (generating motion) according to the number of teeth in both cutter and workpiece (Fig. 1), while the cutter reciprocates for the metal removal action (cutting motion).
