多面加工工件坐标系的设定程序 由于在实际的加工中，用我们的a,A系列机床加工时，带上Ｂ轴，往往涉及到多个面的加工，这时要保证工件的各个相关的尺寸的要求，我们最好能够在机床的加工程序上就建立了一个固定的立体工件模型，这样首先从此模型上保证了零件的各个理想尺寸，同时有利于我们的相关的零件加工的相应调整，最后还有利于我们的程序的编写．现在就相关的问题就由顾工予以讲解． 相关程序的演示及相关注解 相关程序的演示及相关注解 相关程序的演示及相关注解 #20=SQRT[[#29*#29]+[#30*#30]] #21=ATAN[#29]/[#30] #22=#21-#1 #23=SIN[#22]*[#20] #24=COS[#22]*[#20] #31=#24-#7 #[5221+20*[#3-54]]=#23 #[5222+20*[#3-54]]=#[5222+20*[#2-54]]+#5 #[5223+20*[#3-54]]=#31 #[5224+20*[#3-54]]=#1 GOTO99 相关程序的演示及相关注解 Statement Example #1 = 123. #2 = #1 #3 = #2 + 10 G01 X10.
