因工作需要,参加本厂及协作厂产品质量现场随机抽查活动。在车间实际观察中发现,不少青年工人在使用测微量具和游标量具测量工件时存在看来似小,其实不小,不容忽视的共性问题:不能正确使用和选择量具,人为的造成测量误差加大,形成误测,使检测既不能保证测量精度,也不符合检测经济性。众所周知,千分尺、游标卡尺在机械加工、机械制造中使用普遍而且精度较高,几乎人手一把。笔者认为有义务和必要对此问题提出,加以
Due to work needs, participate in factory and collaboration plant product quality random spot checks. The actual observation in the workshop found that many young workers in the use of micrometer and cursors measuring artifacts when there seems to be small, in fact, not small, can not be ignored in common problems: can not correctly use and choose measuring tools, artificial measurement error Increase, forming a misidentification, so that the test can not guarantee the accuracy of measurement, does not meet the test economy. As we all know, micrometer, vernier caliper in the machining, machinery manufacturing used in general and high precision, almost a manpower. I believe that there is an obligation and necessity to put forward this issue, to be
