Verification of a procedure for feedrate scheduling for constant force in 2D milling operations

Abstract

This paper presents a brief overview of the developed procedure for off-line optimization of CNC program. The procedure refers to milling operations in plane z=const, using flat end mills. The goal of optimization is to create modified version of part program, using feedrate scheduling, in order to keep desired milling force component on predefined value along tool path. Detailed experimental verification of this procedure is carried out using a representative example and machining test.
