The CNC lathe feed route refers to the path through which the tool starts from the point of the knife(or the fixed origin of the machine tool) until it returns to that point and ends the processing process. Including the cutting process path and cutting tool cut, cut out and other non-cutting blank path.
The refined feed route is basically carried out along the outline of its parts. Therefore, the focus of determining the feed route is to determine the feed route for rough processing and empty stroke.
In NC lathe processing, the determination of the processing route generally follows the following principles。
1 It should be able to guarantee the accuracy and surface roughness of the workpiece being processed。
Make the processing route the shortest, reduce the empty travel time and improve the processing efficiency。
3 Try to simplify the workload of numerical calculations and simplify the processing process.
For some reusable procedures, subroutines should be used.
