MATHEMATICAL MODELS OF CUTTING FORCES DURING TURNING

Investigation of Cutting Forces during Machining Process by High Speed Turning

This paper presents the obtained mathematical models of cutting forces during machining process by high speed turning as a function of processing parameters v, f, a and re. The machining process by turning is performed on NC lathe using ceramic cutting tool inserts and the workpiece material is C 1630 (DIN C 55). Processing parameters are varied in range between v =300 and 700 m/min , f =0,16-0...

Effect of Cutting Parameters on Cutting Forces and MRR During Turning Hard Alloy Steel With and Without Coolant

This paper investigates the effect of different cutting parameters (cutting speed, feed rate, and depth of cut) on cutting force components and material removal rate (MRR) in dry and wet hard turning processes. The workpiece material, hardened alloy steel AISI 52100, was machined on a CNC lathe with coated carbide tool under different settings of cutting parameters. Three cutting parameters eac...

Multi Objective Optimization of Cutting Parameters in Turning Operation to Reduce Surface Roughness and Cutting Forces

Investigation of Cutting Forces Superalloy Inconel 718

Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investig...

Wear behavior of ZrAlN coated cutting tools during turning

In this study we explore the cutting performance of ZrAlN coatings. WC:Co cutting inserts coated by cathodic arc evaporated Zr1-xAlxN coatings with x between 0 and 0.83 were tested in a longitudinal turning operation. The progress of wear was studied by optical microscopy and the used inserts were studied by electron microscopy. The cutting performance was correlated to the coating composition ...
