MAIN SPINDLE LOAD MONITORING DEVICE FOR MACHINE TOOL

摘要

A main spindle load monitoring device indicates a main spindle load in a machine tool that includes a tool with a plurality of edges on a main spindle and performs a process of a workpiece while the tool rotates with the main spindle. The main spindle load monitoring device includes a main spindle load detecting unit configured to detect a load on the main spindle, a main spindle load conversion unit, and a display control unit. The main spindle load conversion unit is configured to convert a time course of the main spindle load detected by the main spindle load detecting unit into a change of the main spindle load with respect to a main spindle rotation angle. The display control unit is configured to indicate a value of the main spindle load converted by the main spindle load conversion unit on a display screen in a polar coordinates system.
