CMM TERTIAL DATUM EVALUATION TO IMPROVE CNC PARAMETER SETUP

Abstract

The functionality of parts used in different stages of production evolved and improved permanently, due to these modifications it’s required that processes to have less and less time for setups. All this led us to low scrape rate acceptance and management of time during reference changes for dynamic production cells. The processes with multiple operations, different clamping phases and assembling operation give us the information that measurement of this references characteristics can create a looping error due to different alignment system interpretation and all these led to increase setup time of CNC machines. To solve this error, we need to investigate the setup step by step until all the dimensions are conform to the requirements. This article will analyze the different methods used to measure a dimension based on tertial datum represented by a slot and propose a solution to have a simple and better interpretation of alignment system of tertial datum. The importance of the new method developed consist in creation of hi setup speed time and adjustments with focus on all measurement results.
