turning studies of deep cryogenic treated p 40 tungsten carbide Cutting Tool inserts technical communication
Machining Science and Technology, 2009Co-Authors: T Sreerama V Reddy, T Sornakumar, R Venkatram, Venkatarama M Reddy, A SenthilkumarAbstract:In the present work, coated tungsten carbide Tool inserts of ISO P-40 grade were subjected to deep cryogenic treatment at −176°C. Turning studies were conducted on AISI 1040 workpieces using both untreated and deep cryogenic treated tungsten carbide Cutting Tool inserts. The turning performance was evaluated in terms of flank wear of the Cutting Tool inserts, main Cutting force and surface finish of the machined workpieces. The flank wear of deep cryogenic treated carbide Tools was observed to be lower than that of untreated carbide Tools in machining of AISI 1040 steel. The Cutting force during machining of AISI 1040 steel was lower with the deep cryogenic treated carbide Tools when compared with the untreated carbide Tools. The surface finish produced on machined AISI 1040 steel workpieces was superior with the deep cryogenic treated carbide Tools as compared to the untreated carbide Tools.

a dc motor based Cutting Tool condition monitoring system
Journal of Materials Processing Technology, 1999Co-Authors: Tamas SzecsiAbstract:Abstract In this paper a Cutting Tool condition monitoring system for CNC lathes is presented. The system is based on the measurement of the main DC motor current of the lathes. It consists of current and rotation speed sensors, a Cutting Tool – part touch sensor, analogue memory, amplifiers, filters and a personal computer. The system is capable of functioning in three modes depending on the machined surface. It can take into account the part diameter variation and the acceleration of the spindle. The system is trained by a genetic algorithm based fuzzy rule set. The monitoring system can be used in an unmanned manufacturing environment.

automatic Cutting Tool condition monitoring on cnc lathes
Journal of Materials Processing Technology, 1998Co-Authors: Tamas SzecsiAbstract:Abstract This paper addresses the problem of automatically defining Cutting-Tool wear on CNC lathes. The problem is solved by analysing the axial force during the pressing of the Cutting edge of an insert into the workpiece while the Cutting process is stopped. During machining the feed movement is interrupted and the position of the Cutting Tool at this moment becomes a reference point. With no feed movement the rotation of the workpiece continues for a few revolutions, the Cutting edge being moved off the transient surface in the axial direction, after which the rotation stops. With slow axial movement the Cutting edge is pressed into the surface of the workpiece and at the same time the pressing depth relative to the reference point and the axial force are measured. Analysis of the results shows a close relationship between the axial force, measured at a fixed pressing depth and the flank wear of the Cutting Tool. The paper also presents some results on Cutting-Tool condition monitoring using artificial neural networks.
