The feed machining route of CNC lathe refers to the path from the starting point of tool setting (or the constant origin of the machine tool) to the beginning and end of the machining program, including the path of cutting and the path of non cutting empty travel such as tool cutting in and cutting out.
The feeding route of finish machining is basically carried out in sequence along the appearance of the parts. Therefore, the key work of confirming the feeding route is to confirm the feeding route of rough machining and empty stroke.
In the CNC lathe processing, the processing route is generally in accordance with the following principles.
① The accuracy and surface roughness of the workpiece to be processed shall be ensured.
② Make the processing route short, reduce the empty travel time, and increase the processing efficiency.
③ Although the workload of numerical calculation is simplified, the machining procedure is simplified.
④ For some repeatedly used programs, subroutines should be used
