The approach constructs all the feasible fixture plans of a part with linear and circular edges by using the linkage mechanism theory. 该方法利用连杆机构原理自动确定由直线和圆弧组成定位边界的零件的全部候选定位方案。
The start and stop of the machine are carried out by a multiple-disk clutch and the reciprocation of the ram is achieved by a crank connecting link. 本机床的启动与停止用一多片式离合器控制，滑枕的往复运动通过曲柄连杆机构实现。
