Diamond turning of steel alloys is impractical due to catastrophic tool wear caused by a combination of chemical and abrasive wear. In the literature, several modifications of the cutting process have been proposed, e.g. cutting in an inert gas atmosphere, cryogenic cutting and vibration assisted cutting, e.g. elliptical vibration cutting (EVC) [1-5]. In this work, the EVC method was investigat...

Tool wear has great impacts on tool life and cutting parameter selection in the machining process. As ceramic inserts are widely employed efficient machining, it is of significance to predict accurately tools. Crater one most significant modes when turning difficult-to-cut materials at high speeds. The purpose this research demonstrate forming influence mechanisms crater Ti6Al4V with while cons...

Bimetallic parts are used in many industries for weight and cost reduction of workpieces working under high loads and wear. One application for this type of composite material is in automotive industry. In this work the tool wear and cutting forces in the face milling of bimetallic parts made of aluminum and cast iron were investigated. A356 and GG25 alloys that are common materials for bimetal...

In manufacturing by machining, thermal loads on cutting tools can have a major influence on tool wear and hence process cost, especially at higher cutting speeds. An investigation has been undertaken to determine heat partition into the cutting tool for high-speed machining of AISI/SAE 4140 high-strength alloy steel with uncoated and TiN-coated tools. The cutting tests have been performed at cu...

In automation flexible manufacturing systems, tool wear detection during the cutting process is one of the most important considerations. This study presents an intelligent system for online tool condition monitoring in drilling process .In this paper, analytical and empirical models have been used to predict the thrust and cutting forces on the lip and chisel edges of a new drill. Also an empi...

We propose a novel, on-machine method of measuring the profile of the cutting edge of a tool by using the cutting fluid on the tool surface. Despite an environment of on-machine tool profile measurement, it is difficult to measure a cutting edge profile by using conventional optical methods due to interference from the cutting fluid on the tool surface. To overcome this problem, we propose a pr...

Microlubrication minimizes the exposure of metal working fluids (MWFs) leading to an economical, safer and healthy workplace environment. In this study vegetable based lubricant is used to conduct wear analysis during end milling AISI 1018 steel using microlubrication. Solid carbide cutting tool was used with varying cutting speed and feed rate having a constant depth of cut. A full factorial e...

Cutting tool and machining parameters selection are central activity in process planning, which was traditionally performed by numerical control programmers or machine tool operators. The surface integrity has great effect on part quality and the sudden tool failure increases the machining costs greatly. The present paper details the development of a cutting database system with surface integri...
