过去磨削阿基米德凸轮所用的靠模板,是通过划线后逐段修锉然后在回转工作台上用百分表逐段检查,或在座标镗床上进行分度修锉并检查,这样多次才能修好。但一改变其检查点或在任意点检查时,就不能保证达到要求。如工件按5°检查,靠模板也必须按5°修整,即在5°点上是符合阿基米德曲线的。但当工件如改为4°或6°检查时,就不能保证要求,因此整个型面上是波浪起伏的。用这种逐段修磨方法,不但质量不能保证,而且效率也很低,一般修锉一个靠模
In the past, the template for grinding Archimedes’ cams was modeled by scribing and then filing one by one in a paragraph and then using a dial indicator on a rotary table to inspect it in sections or on a coordinate boring machine for indexing and checking Several times to fix. However, it is not guaranteed to meet the requirements as soon as it is changed or inspected at any point. If the workpiece is examined by 5 °, the template must also be trimmed by 5 °, that is, at 5 °, it is in accord with Archimedes’ curve. However, when the workpiece is changed to 4 ° or 6 ° inspection, it can not guarantee the requirements, so the entire surface is undulating. With this piecemeal grinding method, not only the quality can not be guaranteed, but also the efficiency is very low, the general repair file a master
