GearOffice Consulting Services announces an expansion of its products & services and the launch of a new GearOffice website (link below). In addition to the GearOffice computer program for gear hobbing analysis, the new services include gear design, gear processing, gear inspection and process debugging, SPC for gear manufacturing, and training.

The GearOffice principal engineer, Yefim Kotlyar, has over 40 years of experience in the art of gearing. His expertise includes developments of various gear cutting & grinding technologies, development of gear inspection and evaluation technologies, development and implementation of SPC for gear manufacturing processes and design and validation of gears and gearing systems. He is the author and one of the owners of GearOffice computer program. Yefim Kotlyar has served on a number of AGMA technical committees and he has authored many articles on gearing subjects.

The GearOffice computer program was designed to performs various hobbing and gear geometry calculations and maintain Gear/Hob/Machine/Hobbing Project records. The program keeps gears, machines, and hobs as independent objects. It can combine a gear, a machine, and a hob into a hobbing project, to determine (or select) cutting parameters, and calculate the results: cycle time, chip thickness, approach and overrun distances, hob setting angle, feed scallop depth, depth of enveloping cuts, force, torque, as well as tooth thickness/DOP/span. It also determines tolerances based on AGMA/DIN/ISO class and vice versa. Finally, it calculates many important gear geometry characteristics i.e. roll and polar angles, roll length, pressure angle, tooth/space thickness and more for normal, transverse, and axial planes at any gear diameter.
