Error compensation in NC machine tools

Mohamed Rahou, Fethi Sebaa, Abdelmadjid Cheikh, Sid Ahmed Benmansour

Abstract

This work contributes to the development of new approaches to tolerancing for machining using a machine tool with digital control. Our research is focused in two directions. First, it focuses on the manufacturing tolerances. The aim was to establish procedures for validating ranges of light manufacturing dispersions, manufacturing errors and machine tools with digital control, and cover various types of critical tolerances targeted. The second deals with design tolerances, for which we proposed a method for calculating functional tolerances. Keywords: Errors, tolerance, manufacturing.
