Abstract

In this paper surface optimization for the surface roundness has been done by considering the cutting parameters as cutting speed, feed rate and depth of cut. The experiments were performed on a CNC lathe, and the materials used for the experiment is steel St.60, with 100 mm length and 1" diameter. For design and optimize the results experiments used Taguchi method, and to predict the level of significance tests that contribute to the unity of the surface is done by ANOVA with Minitab 15 software. From this research the optimized values contributing as cutting speed 60 m/menit, feed 0.2 mm/rev and depth of cut 0,125 mm respectively. To find out the extent to which the accuracy of the minimum values of surface roundness, then do validation on parameter values corresponding to the optimization of the minimum value of the parameter.Keywords: roundness, cutting speed, feeding, depth of cut, Taguchi.

Abstract

Pipe bending process needs special attention because it makes different mechanical properties. Increasing hardness cause materials brittle. The purpose of this study was to analyze the distribution of force on the part of the pipe as a result of the heating curves and 8000C 6700c with bending angle 900 and 1800. SA 335 is a pipe specimen with the size of outside diameter 44.5 mm and a thickness of 8 mm. At first, the two pipes is heated to the temperature 6700c and 2 other pipes that are heated to 8000C temperature, then 2 pipes bended at each heating temperature 900 and 1800. After that cut pipes to grab third in replication in each condition 4 pipe. From the test results found that the bending angle effect on hardness values. The greater the bending angle, the higher the hardness value.Keywords: bending, hardness, pipe, heating.
