Abstract

This test was conducted to determine the comparison of torque on a 115 cc motorcycle, Standard with different pully degree variations, 14 °, 13.5 °, 13 °, 12 °. With the maximum speed in each different pully test, at the 14 ° degree pully the resulting torque is averaged 6.35 with Rpm 6,637 (The trotle opening is maximum), In the 2nd test using Pully 13.5 ° testing was carried out with Rpm at 5. 900 - 5,980 (Maximum trotle gas opening) produced a torque of 6.47 which is greater than the test using the previous 14 ° pully, but the maximum Rpm produced by the pully with a degree of 13.5 ° mala is slower than testing using a 14 ° pully. From this test, we can see the difference. That using Pully 13.5° the torque is greater but the engine rotation is slower. The 3rd test using a 13 ° pully with a maximum Rpm at 6,500 - 6,700 (maximum trotle opening) produces a torque of 6.29, from this test it can be seen the difference in torque and Rpm produced by a 13.5 ° degree pully with a 13 ° degree pully, where the Rpm is 720 Rpm faster with a difference in torque at a lower rate of 0.18 Nm isbanding diangaka difference with a 13.5 ° degree pully. The 4th test using a 12° pully with a maximum Rpm at 7,140 - 7,190 Rpm (Maximum Gas Trotle Opening) produced a torque of 6.02. From this test, it can be seen the difference with the test using a 13° pully, where the Rpm produced is higher but the torque is smaller, the torque difference is 0.27.

Abstract

In the machining process, the speed grip of the CNC Router spindle on the surface area of the activity entity is very closely monitored and the physical quality of the cutting surface is also on the amount of cutting speed, thickness of the tape and the strength of the film. The aim of the study is to understand the speed grip of the CNC Router on the surface mill system on the surface surface of the activity entity. using spindle speeds of 1000 rpm, 1200 rpm and 1400 rpm. The equipment and materials in this study are aluminum and measuring equipment. Based on the results of the visual study, it was found that the largest and most aggressive flat body was seen at a spindle speed of 1000 rpm, and a stable flat body was seen at a spindle speed of 1200 rpm, then the smallest or strongest flat body was seen at a speed of 1400 rpm while the data from studies using Roughness Tests, it shows that the average Ra point at a spindle speed of 1000 rpm is 0.33 um, at a spindle speed of 1200 the Ra point is 0.30 µm, and at a spindle speed of 1400 rpm the Ra is 0.29 µm. From the results of the study, it was found that the smaller and higher the spindle rotation, the grip on the physical surface on the face mill of the experimental entity and the higher the speed of the spindle, the smoother the surface, and vice versa, the smaller the spindle rotation, the more aggressive the surface. Keywords: Spindle Speed and Surface Roughness.
