The Design and Computing Program for Modification Coefficient of External Gear Shaper Cutter

It is an important job for designing the gear shaper cutter to compute modification coefficient. The selecting principle of gear shaper cutter's modification coefficient and the four restricted conditions: sharpening the top gear, the interference of the cut gear's fillet curve, undercut and the top cut are discussed. The computing formula for the maximal modification coefficient of the new cutter's designing and the minimal modification coefficient met the final indispensable intensity of the shaper cutter is introduced; the computer aided program is workout to make the design of shaper cutter easy and quick and estimate the feasibility of design expediently.
