Identification of Residual Stress in the Production of Molding Tools by Turn-Milling Technology

Abstract

This article describes how to plan the tool path and analyze the surface of the machined part by working simultaneously on two basic operations such as milling and turning. New machine tools allow parallel processing of both multi-axis tools at the same time, it is a production technology in which the workpiece and the tool are simultaneously rotating. This relatively new turnmilling technology could be an alternative to increasing productivity in many applications. Especially in cases involving heavy-duty materials or large diameters of machined surface. The aim of this study is to explore this new technology, especially with regard to the increased precision and quality of the surface of the workpiece. Experimental results show that the combination of these two operations is suitable for precise machining of rotationally symmetrical workpieces with high surface finish.

Identification and Analysis of Defect in Forging Tools by Non-Destructive Detection Method

“…It is a nondestructive testing method and has considerable importance in improving quality and reliability in industry, especially in engineering. It is one of the most important methods of nondestructive testing of materials and can detect material discontinuities resulting from the production process well as from mechanical stress during operation [5,8].…”
