摘要: 讨论了传统锁模力重复精度测试方齿的特点,使用瑞士Baumer 锁模力感测仪研究了锁模力重复精度的影响因素。结果表明,开合模位置以及开合模速度的变化对锁模力重复精度的影响可以忽略不计;基于Baumer锁模力感测仪的锁模力重复精度测试方法相比于传统测试方法具有操作简单、搞笑精确的特点。

Abstract: Charalcteristics of conventional measurerment methods of clamping force repeatability was discussed. Influencing factors on clamping force repeatability were invest igat ed by Baumer strain clamps (Switzerland) . It was found that the influences of variatlons of mold closing/ opening position and speed could be neglected. The test methods of clamping force repeatability based on Baume strain clamps had characteristics of easy operation and high accuracy.
