Abstract

The purpose of this study was to determine the effect of feed rate and depth of cut on the surface roughness of Al-Mg aluminum using a DIY CNC Milling Machine and Krisbow Universal Milling Machine as a comparison. The open-loop control system is a control system used in the design of DIY CNC Milling machines. A PC with Mach3 software is used as a PC Based Direct Digital Controller to control the system. In this study, the feed rate variation 24 mm/minute and 42 mm/minute and depth of cut 0.25 mm, 0.5 mm, and 0.75 mm were used. After the face milling process, the surface roughness test was carried out using the Mitoyo Surface Roughness Tester to determine the level of surface roughness of the machining results the DIY Milling Machine and Krisbow Universal Milling Machine as a comparison. The results showed that as the feed rate and depth of cut increased, the surface roughness values of both tools increased.

Highlights

The potential that exists in Kedawung Village, Nglegok District, Blitar Regency, Indonesia is for fruits, tourism (Penataran and Mount Kelud), fisheries, and animal husbandry
The highest surface roughness (Ra) on the CNC Milling Machine prototype is found in the specimen groove with a feed rate variation of 42 and a depth of cut of 0.75 which is equal to 0.884, and the lowest surface roughness (Ra) on the CNC Milling www.techniumscience.com
There is no significant difference in the surface roughness of the machining results between the two tools, but the surface roughness results using DIY CNC are lower than the surface roughness results using conventional machines

Summary

Introduction

The potential that exists in Kedawung Village, Nglegok District, Blitar Regency, Indonesia is for fruits (mangosteen and pineapple), tourism (Penataran and Mount Kelud), fisheries, and animal husbandry (raised chickens and ducks). Blitar Regency is one of the centers for broiler and duck farming in East Java. Duck farming is a side job for the community apart from farming as the main occupation. The result of raising ducks is one of the pillars of the community's economy. Hamlet Salam is one of three hamlets in the Kedawung District, a duck, and salted egg farming center. The development of machining process technology in the livestock industry, especially in the duck feed and salted egg industry, currently requires a numerical control system with computers on CNC (Computer Numerical Control) machine tools. CNC Milling Machine is an automated machine tool equipped with a computer-based control system that can read and interpret G&M code to regulate work as desired [1]
