【Abstract】 The types,features and coordinate equations of closed profiles with isometric characteristics were introduced. As the isometric-shaped hole machined with 3-axis NC milling machine,the trace of tool,calculation of programming coordinate and the architecture of computer-aided programming were analyzed. A sample of NC program for machining isometric-shaped hole was illustrated also.更多还原
