Abstract

The magnitude of the corner radius (nsr), the cutting speed (V), the feeding motion (f), and the cutting depth (cut depth), will offend the cutting edge wear (Vb) and the quality of the finished product with Al 6061-T6. The problem of the effect of a large corner radius (nsr) on wear and tear. (Vb) on the Lathe process which affects the quality of the product. Research Objectives to produce the following wear results (Vb) on the quality of the lathe products; It produces the characteristics of the chisel root wear (Vb). Benefits Research to know benchmark tobacco (Vb) benchmarks on the quality of the lathe products, and the wear and tear feature of wear (Vb) and benchmarks. The results achieved in the feeding motion have a significant effect on the wearing of the chisel roots (Vb), evidenced by the presumption of the equation y = Vb (Um) = -0.00105 + 0.000186 f (mm / put). The value of surface roughness (SR) is evidenced by the assumption of equation y = SR (Um) = -5.22 + 0.00440 n (Put / min) + 5.55 nsr (mm) + 0.0660 f (mm / put0.000002 n (Put / min) * N (Put / min) - 0.0814 nsr (mm) * f (mm / put) Response response at rotation (n) 750 put / min, corner radius (nsr) 0.4 mm and feeding motion (f) 80 mm / Input to the surface roughness value (SR) 1.010 μm, cutting edge wear (Vb) 0,1536 μm Morfologi wear cutting edges with above condition no BUE (edge bush) so no abrasive, adhesion and Flaking occur, Chiping in the field of anger and the main plane, so stacking the corner radius (nsr) is very small also affects the decrease of product quality quality.Response growth at round (n) 1000 put / menit, corner radius (nsr) 0.4 mm and feeding motion (F) 70 mm / put surface roughness results (SR) 1.085 μm, cutting edge wear (Vb) 0.1210 μm Morphology of upper edge wear occurrence of BUE (bult edge up) embodiment of abrasive, adhesive I, diffusion and flaking, Chiping in the field of anger and the main field, so translating the corner radius (nsr) in the main field, the impact on the decrease of product quality.

Abstract

Research lathe machining process, carried out on workpiece material T-6061 aluminum and the HSS. The problem is that a large beaker radiuschip, spindle rotation and eat optimum motion to produce lathe Al-6061 with a surface that is smooth, safe and capable of producing a high production capacity with a cutting depth (depth of cut) is constant.Optimized cutting parameters selection is very important to control the quality of the product surface cylindrical form of Al-6061 is to optimize for spindle rotation, movements meal and corner radius (Chip) furious breaker using two measures of performance, metal removal rate and the surface roughness.Response Surface Methodology (RSM).  Alleged best regression model to speed snarled income (MRR) at a rate of 95% at n = 900 rpm, f = 115 mm / put and RCB = 1.25 mm is = . While allegations of the best regression model for surface roughness (SR) at a rate of 95% at n = 900 rpm, f = 115 mm / put and RCB = 1.25 mm adalah: +0,14x2x3.  A regression model be able to describe the relationship between the combination of cutting parameters and radius chip breaker produced maximum metal removal rate and minimum surface roughness. Spindle rotation is the dominant influence on the surface roughness, whereas eating motion and spindle rotation is very influential on the metal removal rate, followed by radius chip breaker. Results obtained by iterative optimization using Response Optimizer for surface roughness (SR) at n = 950 rpm, f = 90 mm / put and RCB = 1.44 mm resulted SR 0.360 μm, while the Response Optimizer on MRR at n = 950 rpm, f = 90 mm / put and RCB generate MRR = 1.44 mm 39.55 mm 3 / sec. Key words :  Material  Removal  Rate,Optimizer Response, chip  breaker, surface roughness
