Dimensioning the NC: Axes of a Radial Cam Grinding Machine

The computer program deals with the dimensioning of drives and optimizing structural nodes parameters of the radial cam grinder controlled with a three-axis control system. Source information for dimensioning drives is the radial cam contour and a number of structural and technological parameters, such as maximum spindle torque, grinding tool diameter, feed along the cam surface, etc. Conceptually, it is considered with mechanisms with constant gear between the working motion of NC axes and the servo motor (gearboxes and linear ball screws). The calculation results are performance characteristics for each servo motor and the optimized parameters of structural nodes. These parameters are driving torques (maximum, effective) and speed (maximum), constant gear ratios, pitch and diameters of ball screws, etc. It is also considered the positional deviation caused by the compliances of the gear mechanisms.
