MACHINE TOOL SYSTEM AND SURFACE ROUGHNESS DETECTION METHOD

摘要

The present invention addresses the problem of providing a machine tool system capable of suitably measuring the shape of a workpiece, providing a machine tool system for suitably calculating the surface roughness of the workpiece and a surface roughness detection method employing the machine tool system, and providing a machine tool system comprising a coolant liquid contamination evaluation device with which a sensor can be provided to a tank main body and which is capable of evaluating the degree of contamination of a coolant liquid. The machine tool system comprises a workpiece support device 20 that rotatably supports a workpiece W, a grinding wheel 40 that serves as a tool for processing the workpiece W, a detection unit 120 that performs non-contact detection of the workpiece W, and a calculation unit 220 that extracts shape information of the workpiece W or calculates the surface roughness of the workpiece W on the basis of a detection result from the detection unit 120.
