Related Glossary Terms

  • feed


    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • grinding


    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

  • hardness


    Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.

  • tensile strength

    tensile strength

    In tensile testing, the ratio of maximum load to original cross-sectional area. Also called ultimate strength. Compare with yield strength.

Calculation Tools for the Gear Pro

Gleason announces the new “Gear Calculator App”. This free mobile app bundles simple calculation tools to make gear manufacturer’s daily work life more efficient and productive. The Gear Calculator toolbox includes calculations for gear inspection values like addendum modifications, base tangent lengths and measurement over balls, it provides a hardness converter including tensile strength, Rockwell, Brinell or Vickers, the calculation of rotational speeds, calculation of deviations within gear quality standards, feed rates and chip thickness when gear hobbing, and a twist calculator to determine the natural twist when threaded wheel grinding. Future updates are planned to make the app even more useful.

The Gear Calculator App works online and offline, it runs on pcs/notebooks as well on mobile devices with Android and iOS. The App must be connected online to install future updates. Please note that you will need a current browser/version to view the Gear Calculator App. When starting the App for the first time it is necessary to register and log into “MyGleason” (for both the PC/notebook version as well as the Mobile App).

Installing the App on Your Mobile Device

  • For Android, open the browser menu and select 'Add to Start Screen'.
  • For iOS select 'Add to home screen' in the share menu. A new icon called Gear Calculator will be created on your home screen or App Drawer.
