Abstract

This study aims to provide value and knowledge to students or machine operators at a cutting speed level what is a good cut on the workpiece ST-37. During this time students and machine operators do not consider the use of Cutting Speed ​​values ​​in an analytical manner when doing the Freis process. The experimental method was used in this study using the object of research on ST 37 steel which was made sliced ​​at the surface. The method used in making cuts uses the downcut method which varies the cutting speed. The test results obtained data that the average price of roughness per rotation speed is (∑Ras) = ​​4.01μm for Cs 20 with a rotation speed of 530.78Rpm. (∑Ras) = ​​2.84μm for Cs 25 with a rotation speed of 663.48Rpm. (∑Ras) = ​​2.59 μm for Cs 30 with a rotation speed of 796.18Rpm. With a roughness class on N8. So the conclusion in this study the higher the rotational speed of the machine which is affected by high cutting speed, the smoother the workpiece surface will be.
