How to Improve Machining Precision of Machine Tools Using On-machine Measurement and Iterative Machining

摘要

The present invention improves the machining precision of a machine tool by measuring the workpiece by using a measuring instrument without changing the machining coordinates without separating the machined workpiece from the machine tool after machining the workpiece, and then repeatedly machining the workpiece with error compensation The present invention relates to a method for performing precision machining of a machine tool using on-machine measurement and repetitive machining. The present invention relates to a first machining step for machining a workpiece using a tool, and a workpiece processed in the first machining step. An on-machine measuring step of measuring the dimensions using a measuring means without being separated from the machine, and a process of calculating an error between the dimensions of the workpiece measured in the on-machine measuring step and the dimensions of the workpiece to be processed. Error compensation process for calculating the error compensation tool path using the error calculation step and a predetermined error compensation algorithm. Measurement and compensation of machining errors in machine tools in a short time, including an error compensation machining step of reworking the workpiece using the tool according to the path calculation step and the error compensation tool path calculation step. There is an advantage that can be processed with high precision.
