Problems solved by technology
It is obviously very difficult to disassemble and re-clamp if off-line measurement and compensation processing are used. At the same time, it will consume time and effort and reduce processing efficiency. Therefore, it is necessary to study ultra-precision in-situ measurement technology for large roller molds
[0003] At present, the existing in-situ measurement method of roundness error is difficult to measure, and the measurement error is relatively large

According to the device, the measurement difficulty is effectively reduced, and the measurement precision is improved.
Description
technical field [0001] The present application relates to the technical field of on-site measurement of roundness errors, in particular to an on-site measurement device and method for roundness errors of roller molds. Background technique [0002] The ultra-precision machining of roller molds is one of the key difficulties in roller molding technology. In order to process high-precision and large-size roller molds, it is necessary to evaluate the shape accuracy of the processed roller molds. The shape accuracy of the roller molds reflects the relative deviation between the actual contour and the ideal contour of the roller mold shape. Compensation processing is required for roller molds that do not meet the precision requirements. The roundness error is a key part of the shape error of the roller mold. Generally, the roundness error of the processed workpiece is measured by a high-precision measuring instrument. However, due to its large size, the roller mold Shape accurac...
