SIZE CORRECTING APPARATUS FOR CNC MACHINE AND METHOD THEREOF

摘要

PURPOSE: A device for correcting a dimension of computerized numerical control and a method thereof are provided to reduce processing defects due to human error by correcting a dimension by automatically reflecting a value to be converted through an automation tool in the process of correcting a dimension of a router process program. CONSTITUTION: A device for correcting a dimension of CNC(Computerized Numerical Control) comprises an aberrometer(1), a tool(2) for correcting a dimension, and a CNC processing unit(4). The aberrometer measures errors of a processing material. The tool for correcting a dimension extracts correction items through product structure analysis of the processing material. Final dimension correction data on the correction items of the processing material is generated and is output based on the error data. The CNC processing unit processes the processing material depending on the final dimension correction data.
