PENGARUH VARIASI PUTARAN SPINDEL TERHADAP GAYA POTONG PADA PROSES PEMESINAN

Abstract

The turning process is one of the most important machining processes in the industrial world. In this process, a change in shape is carried out by removing some of the material in the form of industrial machine tools. Inappropriate selection of the shape/type of tool, workpiece material, and cutting conditions will affect the characteristics of the tool. In the study, it was found that the rotational speed was 90,110,155,190 rpm, with a depth of cut of 0.3 mm at a feed rate of 0.023 mm / rev against different specimens, namely Dural Aluminum (Al 2024), Pure Aluminum (Al 1100) using a chisel insert type DCGT 070204K. -10 and DCMT 070202 M-20 with conventional lathe type Emco Maximat V - 13 IP 54. Data retrieval uses three sensors, namely a load cell sensor for cutting force, and the photoelectric counter module for rotation (rpm). The results showed that each specimen tested had a different value in each test experiment, such as testing on Pure Aluminum (Al 1100) specimens with a cut depth of 0.3 mm and rotation variations of 90, 110, 155, and 190. rpm can be seen in DCMT tool that the cutting force is greater than the DCGT tool. The cutting force produced on the DCMT tool blade is 9.91 N with a rotation of 110 rpm and at 190 rpm the DCMT tool gets a force of 6.83 N. It can be concluded that at low rotation the cutting force that occurs will be greater because of the vibrations that occur bigger.
