The invention discloses a Pin-free positioning automatic expansion and shrinkage drilling manufacturing method. The production plate is divided into a plurality of areas; each area is independently provided with a positioning hole; the CCD camera is used for grabbing and identifying the positioning hole in each area in the plate; corresponding drilling expansion and shrinkage ranges are given according to actual lamination expansion and shrinkage values of all areas, so that one-to-one correspondence between the drilling expansion and shrinkage ranges of different layers and actual expansion and shrinkage is achieved, and the rejection rate of drilling deviation caused by the difference between lamination expansion and shrinkage and actual production plates is reduced. 本发明公开一种无Pin定位自动涨缩钻孔制作方法，将生产板划分为多个区域，每个区域单独设计定位孔，通过CCD摄像头对板内每个区域的定位孔进行抓取识别，依据各个区域层压实际涨缩值来给定对应的钻孔涨缩程式，以此实现不同层钻孔涨缩程式与实际涨缩的一一对应，降低了层压涨缩与实际生产板的差异导致的钻孔偏报废不良率。
