Cutting Forces and Tool Wear Investigation for Face Milling of Bimetallic Composite Parts Made of Aluminum and Cast Iron Alloys
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...
متن کاملFatigue Behaviour of Synthetic Nodular Cast Irons
A. Vaško, L. Trško, R. Konečná, Faculty of Mechanical Engineering, University of Žilina, Žilina, Slovak Republic The paper shows the influence of charge composition on microstructure, fatigue properties and failure micromechanisms of nodular cast irons. The additive of metallurgical silicon carbide (SiC) in analysed specimens increases the content of ferrite in the matrix, decreases the size of...
متن کاملEvaluation of Flank Wear of Iron-rich Binder Carbide Cutting Tool in Turning of Titanium Alloy
Despite the fact that Titanium material has been considered as difficult to cut material, its usage has been increasing day by day in all engineering sectors; wherever criticality is encountered. Many studies are going on in view of increasing tool life at high cutting speed to improve productivity. In this study, attempt has been made to see the effect of iron as a partial substitution along ...
متن کاملDelamination Wear Mechanism in Gray Cast Irons
An investigation of the friction and sliding wear of gray cast iron against chromium plated cast irons was carried out on a newly constructed reciprocating friction and wear tester. The tests were the first to be done on the test rig under dry conditions and at the speed of 170 cm/min, and variable loads of 20-260 N for a duration of 15 min. to 3 hours. The gray cast iron surfaces worn by a pro...
متن کاملCutting Forces in Hard Turning Comprising Tool Flank Wear and Its Implication for the Friction between Tool and Workpiece
Original scientific paper In this paper, the orthogonal cutting force model is proposed comprising forces due to flank wear in addition to the forces for chip formation during the hard turning of round bar made of steel 60WCrV7 hardened at 55+2HRc. Cutting force model includes two tool conditions: perfectly sharp tool with VBB = 0 and tool with maximum permissible flank wear VBBmax. Based on cu...
