用线切割机床加工各种成形车刀,根据加工零件的不同,车刀要有不同的后角。在用线切割机床加工此类刀具,需在XY平面,在XZ、YZ方向上使刀体倾斜某一角度。然而,要精确地控制XZ、YZ方向上的倾角,就不可避免地给编制程序带来困难,并给加工后的成形车刀造成尺寸和形状上的误差。在工作实践中,根据自己的一些体会,设计了一种在XY、XZ、YZ平面均可自由调节角度的定位支架。方便地解决了在加工成形刀具时,能较精确地控制主后角和侧后 With wire-cutting machine tools for processing a variety of forming turning tools, according to the different processing parts, lathes have different relief angle. In the use of wire cutting machine tools such tools, in the XY plane, in the XZ, YZ direction of the knife tilted at an angle. However, precisely controlling the inclination in the XZ and YZ directions inevitably causes difficulties in the programming process and causes dimensional and shape errors in the finished forming turning tool. In practice, according to some of my own experience, we designed a positioning bracket that can freely adjust the angle in XY, XZ, YZ plane. Conveniently solved in the processing of forming tools, can more accurately control the main posterior horn and lateral
