摘要： A machine tool controller is provided that includes a processor configured to execute a sequence of instructions in accordance with an operating program and a user program. A volatile memory temporarily stores instructions and data during execution of the sequence of instructions by the processor, and is coupled to the processor via a first interface. A first non-volatile memory stores the operating program and is coupled to the processor via a second interface. A second non-volatile memory stores the user program and is coupled to the processor via a third interface. A video controller is configured to control a user display in accordance with display data generated by the processor and is coupled to the processor via a fourth interface. A dual-port memory is coupled to the processor via a fifth interface and couples a serial bus controller configured to control communications with an external device via a serial bus to the processor. An external bus interface is configured to communicate control commands for controlling a machine tool generated by the processor via an external bus and is coupled to said processor via a sixth interface.

摘要： The ratio of executed to skipped measurement movement commands required for actual measurement and a correction value when skipping a measurement movement command are determined and then updated according to past (hysteresis) measurement data. The actual thermal displacement measurement during an executed measurement movement command is performed at a proper rate to improve the machining efficiency of an NC machine tool and minimize an error due to the correction.
