Abstract

CNC machines are computer-controlled machines that can understand the N and G codes (Gcodes) that regulate the machine tool system, (program motion pointers using numbers and letters to cut rotating workpieces), the machine works according to code commands. The code programme used is G75 for the groove making process and G97 for the CNC Turning process. The research aims to determine the variation of spindle rotation on S45C carbon steel. The speed variations used are 1266 rpm, 1066 rpm, 866 rpm. With a depth of cut of 0.4 mm and a feeding of cut of 0.15 mm and the insert used is an insert with the Iscar brand. The average value results obtained from the testing process using a roughness test tool (stylus). The lowest roughness value at 1266 rpm spindle rotation is included in the roughness class, namely N7. The highest roughness value at 866 rpm spindle rotation is included in the roughness class, namely N8. While the intermediate roughness value at 1066 rpm spindle rotation is included in the N7 roughness class. The effect of roughness results on objects, namely, the higher the spindle rotation, the lower the value of the roughness results, on the contrary, the lower the spindle rotation, the rougher the roughness value in the turning process.

Abstract

The use and utilization of steel in the industrial world is very extensive because steel has unique properties, especially its strength. All tooling equipment cannot be separated from the engineering process and repair in the event of damage, namely by welding. One of the things that must be considered in welding is the cooling process. The purpose of the research was conducted to determine the effect of the cooling process on welding on the tensile strength of medium carbon steel using palm waste as a cooling medium. Tensile test samples were made with 3 variations of cooling media (PKO 100%, PKO75%, PKO 50%) using a HUNG TA HT-8503 machine. The highest tensile strength value was obtained from the 75% PKO variation with a tensile strength value of 345.58 Mpa. While the lowest tensile strength value is obtained from the 50% PKO variation with a tensile strength value of 232.28 Mpa.

Abstract

Vocational education in the senior level, namlely Vocational High School (SMK), is designed to prepare graduates with high skills who are ready to compete in the work zone, both with competence and through entrepreneurship in order to face the demographic bonus. SMK Negeri 1 Bangkinang as a partner of the Politeknik Kampar has a major in the Mechanical Engineering. Generally, the major of Mechanical Engineering will be prepared in with competencies of Computer Aided Design (CAD). However, there are limitations to apply Solid Works software, which is currently in great demand in the industry. Therefore, the The major of Maintenance and Repair Engineering Politeknik Kampar participates in improving the competency of students at SMK Negeri 1 Bangkinang Kota through CAD Static Simulation Training activities using Solidworks Software. The training activity material contains an introduction to Solidworks, static simulation theory, namely stress, strain and deformation. At the end of the training activity session, an increase in partner competency was obtained regarding the use of Solid Works software in image creation and static simulation. Evaluation of activities through partner satisfaction questionnaires also found that partners were 100% satisfied with the PkM activities carried out.

Abstract

Electrical energy is a primary source of energy in daily life, with various electrical devices supporting human activities. Sometimes, electrical equipment experiences damage, with repair risks ranging from small to large scale. For damage with medium to large-scale risks, specialized experts are usually needed for repairs. However, damage to electrical installations with small-scale risks should be manageable by household members, especially housewives. Many housewives are afraid and do not understand how to handle electrical issues, even though they are active at home every day. Therefore, there is a need for training and counseling on simple electrical installations so that they can handle it confidently and safely. One form of training that can be provided is the creation of an electrical outlet set for PKK mothers in Muarajalai Village, Hamlet IV. This training aims to equip the PKK mothers with the skills and knowledge about tool specifications, tool functions, and safety procedures when using electrical equipment. With this training, it is hoped that they will be able to maintain and repair simple electrical installations at home without relying on experts, while also increasing their confidence and independence in handling everyday electrical problems.
