Simple Discriminatory Methodology for Wear Analysis of Cutting Tools: Impact on Work Piece Surface Morphology in Case of Differently Milled Kinetics Steel H13

Abstract

Recently, there is growing interest in optimisation of finishing process thanks to the technologies to follow online the wear of cutting tools. In the present paper, one of the cheapest and simplest non-contact methodologies is described in detail and investigated with robustness evaluation. To simulate the finishing operation of a die, in this study, two cavities were designed in AISI H13 steel. Different inserts corresponding to PVD-(Ti,Al)N coated cemented carbide tool were tested. The described methodology is easy to be applied in manufacturing cutting machining with the opportunity to be implemented on machining processes to follow reasonably wear process of cutting tools.

The Study on Feasibility and Welding Characteristics of GMAW Surfacing Remanufacturing of H13 Steel Cutter Ring of TBM Hob

“…This experimental phenomenon is basically consistent with the Coatings 2021, 11, 1559 4 of 16 numerical simulation of Ying et al [16] and Cho et al [17], that is, the temperature in the welding zone is the highest and the surrounding temperature decreases in turn. The reason is that the heat transfer diffuses from the high temperature zone to the low temperature zone [18]. When the heat energy of the surfacing layer diffuses to the substrate, a new high temperature zone will be formed, and the temperature of the surfacing zone will drop sharply through heat transfer and heat exchange with air, thus the temperature of both sides of the surfacing layer in Figure 2b is higher than that of the surfacing zone.…”
