Abstract

The invention discloses a workpiece for thermal error detection, a detection method and a processing method. The workpiece comprises a workpiece body, wherein the workpiece body comprises a prism, the axis of the prism is provided with a central through hole for a clamp to clamp, the side surface of the prism is provided with a color coating; according to the detection method, thermal error data can be obtained by judging the surface abrasion condition of the workpiece body, and detection of the thermal error data of the machine tool under the actual working condition under the condition that cuttings and cutting fluid exist is achieved; and according to the processing method, recycling of the workpiece after error detection is achieved, social resources are saved, and operation and execution are easy.

Description

technical field [0001] The invention relates to the field of thermal error detection, in particular to a workpiece used for thermal error detection, a detection method and a processing method. Background technique [0002] The thermal error of the machine tool refers to the thermal deformation of the spindle due to the rotation of the spindle and the heat generated by the bearing and other components. Thermal error is one of the main sources of machine tool error, and the error caused by temperature can account for 75% of the total geometric error of the machine tool. [0003] Existing thermal error detection of machine tools is mainly through direct measurement by non-contact sensors. During the inspection, the mandrel is installed on the spindle, and the machine tool runs idling (without actual cutting and without turning on the cutting fluid). For example, use an eddy current sensor to measure the thermal error of the mandrel in an idling state, use an inductance microm...
