Abstract: In order to increase the precision of the mold for powder
metallurgy gears, use the CNC form grinding technique with a
plate-shaped grinding wheel to produce the mold. A line-cutting model
for calculation is put forward for the profile calculating. After
transferring the known profile to the plane for calculation, use a
numerical simulation method to calculate the profile of the grinding
wheel. A profile calculating, profile editing and error analyzing
software is also programmed. The calculating and error analyzing example
of a mold that z is 44, mn is 1.5 mm, a is 20° and b is 30° using this
software shows that the calculating error can be under 0.000 1 mm and
the method is precise enough to meet the requirements of high quality
gear molds.
