EFFECT OF CURRENT AND WIRE SPEED ON SURFACE ROUGHNESS IN THE MANUFACTURING OF STRAIGHT GEAR USING WIRE-CUT EDM PROCESS
Abstract
The gears are an important part of a mechanism. Making gears requires high
precision to avoid backlash. The machining process that can produce high precision is the
process of Wire cut EDM. This study aims to determine the roughness of the workpiece
surface and investigate the effect of current and wire speed on the roughness of the straight
gear surface through wire cut machine EMS 45. The wire cut machining parameters used are 3,
5, and 7 amperes for current, and wire speed of 8, 10, and 12 mm/min. While the Wire material
is a type of brass with 0.25 mm in diameter. The results presented that the increased use of
current and wire speed will result in lower surface roughness, and vice versa. Therefore, it can
be concluded that use low machine parameters to produce a smooth workpiece surface.
