机械加工中,由于受机床进给方向的限制,在加工工件上的斜孔时往往需要转动工件或刀具以适应加工的要求。这种在加工过程中工件或刀具的转动角度叫做工艺角度,由于工件在机床上定位条件的不同,图纸上给出的角度一般不能作为工艺角度,需要采用一定的方法进行换算,以便使工件的位置符合加工的需要,本文介绍用图解法求斜孔工艺角度的方法。 In machining, due to the limitation of the feed direction of the machine tool, it is often necessary to turn the workpiece or the tool to meet the machining requirements when the inclined hole in the workpiece is machined. This process in the workpiece or tool rotation angle is called the process point of view, due to the different positioning of the workpiece on the machine, the drawings given angle generally can not be used as the process point of view, you need to use a certain method of conversion, so that the workpiece Location in line with the needs of processing, this article describes the use of graphic method oblique angle hole process method.
