Title: Machine tool copying control - superimposes tool centre related angular velocity onto signal representing translation velocity
IPC: B23Q35/123
Filed: 1975-07-23
Abstract: A table carries the workpiece and the template, and is slidable with drives fed from amplifiers. The amplifiers receive control signals from a device which contains a connection for the incoming signal from a sensor rigidly connected to the tool. The control device compares the signal from the sensor with one representing the required sensor deviation and a signal representing the required translation velocity. From the comparison control signals are computed and fed into the amplifiers. The superimposing of the two signals is effected by an addition circuit with one input connection for the signal representing the required feed velocity and the other input connection for the signal representing the angular velocity.
