摘要
在硬质合金可转位刀片国标中,没有对测量装置提出几何精度要求,这使测量m偏差值欠准确可靠性。本文从误差分析出发,解决了测量中各元件的误差值,将给刀片加工和检验带来有益的经济效果。
In the International standard of ndexable carbide nseris there isno geometric accuracy of measuring units. It results in the measurement of devi-ation value m loses its accuracy and reliability. This problem was solved by me-ans of error analysis. It will bring about great economic effect in processing andtesting tips.
