CNC lathe feed processing route refers to the path that the turning tool moves from the tool setting point (or the fixed origin of the machine tool) until it returns to this point and ends the processing program, including the path of cutting processing and non-cutting processes such as cutting in and out of the tool. Empty travel path.
The feed route of finishing machining is basically carried out sequentially along the contour of its parts. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and empty stroke.
In CNC lathe processing, the determination of the processing route generally follows the following principles.
① The accuracy and surface roughness of the workpiece to be processed should be guaranteed.
② Make the processing route the shortest, reduce the idle travel time, and improve the processing efficiency.
③ Try to simplify the workload of numerical calculation and simplify the processing procedure.
④ For some reusable programs, subroutines should be used.
