English Abstract

In this thesis, an attempt has been made to investigate and simulate the influence of coated layers, cutting speed and feed rate on the cutting force components in orthogonal turning process using Tungsten carbide (WC) cutting tools when machining AISI 1010 steel.

A series of experimental and numerical tests have been done with four types of inserts including uncoated, coated tool with (TiN), (TiN /TiCN) and (TiN /Al2O3/ TiCN) using the special FEA software (DEFORM-2D), which is based on Lagrangian formulation.

Cutting conditions were selected to be five different cutting speeds (45, 65, 97, 145, and 206 m/min.), five different feed rates (0.03, 0.06, 0.1, 0.16, and 0.2 mm/rev.) and at width of cut (1.2 mm).

The results show that the minimum force is achieved when using TiN/TiCN insert compared with other inserts in all cutting conditions.

The cutting force components (tangential and feed force) are decreased by (41%and 55%) respectively when the cutting speed increases from (45to 206) m/min.

while the cutting force components (tangential and feed force) are increased by (424 % and 475%) respectively when the feed rate increases from (0.03to 0.2) mm/rev.

The maximum relative difference between simulated and measured values is less than (17%).
