Experimental and Numerical Study of Different Methods' Effects on Lubricant Flow on Temperatures and Strains of Turning Cutting Tool (HSS)

Abstract

The aim of the present study is to facilitate the machining process of cast steel (HSS) through cooling and lubricating by compressed air with liquid in three directions and consisting of (oil, soap, carbolic acid, and sculpture) and was compared with the lubricant process in one direction and at different cutting speeds (2.08, 6.25, 10.4, and 14.16 m/sec). The Auto Desk Inventor programme is used to simulate the cutting process by applying cutting forces to the tool's shear surface. The interface equipment is used to measure cutting tool strains by the response of a strain gauge and the Arduino equipment to measure cutting tool temperature. In addition, the tool strain equations were used assuming that the cutting tool is fixed between the two walls (fixing region and surface of the workpiece) to get the best results at the same speed. The results refer to the lubricant in three directions, which is better than one direction due to decreasing cutting tool strain, reaction of cutting force on the shear surface of the cutting tool, and cutting tool temperature. The experimental results show that a cutting speed of 10.4 m/sec is the best for the cutting process. Furthermore, the numerical results are converged with practical results in a small correction factor (0.428), preventing the tool from vanishing.

Experimental and Numerical Study of Sudden Stop Case for Twist Drill Tool and Treated by Lubricant

“…The theoretical results of maximum rotational shear strain values (0.0036, 0.0036, 0.0036, 0.0047) and comparison with experimental strains, where the correction factor is (R2=0.9) as shown in Table 3, where this refer to high accuracy between the results. Figures 12,13,14,and 15 show auto desk inventor simulation results with the same different speeds, with strain values of (0.0034, 0.002487, 0.003483, and 0.004476) respectively.…”

Experimental and Simulation Study to Reduce Required Bending Force in Air Bending Die by Using Annealing and Rectangular Hole

“…There are three different types of bending die in metal forming process: air die bending, V die bending, and wipe die bending. The air die bending, which is used in the current study only, is a flexible die where the bending angle changes while the punch travels until the sheet metal angle becomes the same as that of the punch, as illustrated in Figure 2 [13][14][15][16]. The process of air bending begins with the maximum bending force (Fmax), as shown in Eq.…”
