Zusammenfassung:	A machine tool for performing a predetermined machining cycle includes a feed means for effecting relative movement between a work support and a tool support. A first timer is timed out after a predetermined time period from the start of a machining cycle for setting a constant machining cycle time. A second timer is timed out after a predetermined time period from the start of a machining cycle for setting at least one check point during a machine cycle. Any difference between the predetermined machining cycle and an actual machining cycle is detected at the check point. The actual machining cycle is then compensated to perform the predetermined machining cycle.
