Abstract

The results of the minimum surface roughness in the MORI SEIKI SL-25 CNC machining process, the parameters of the MORI SEIKI SL-25 CNC machining process are adjusted in order to obtain a minimum workpiece surface roughness reaction. The research that has been tried aims to ensure the contribution of the CNC MORI SEIKI SL-25 machining process parameters to reduce the alteration of the workpiece surface roughness reaction simultaneously. As well as setting the right parameters of the CNC MORI SEIKI SL-25 machining process parameters in order to obtain a minimum workpiece surface roughness. The machining process parameters that were varied were cutting speed, feed depth and feed motion. The experimental design was inaugurated based on the Taguchi method and in the form of an orthogonal matrix L9 (33). The analysis used is Taguchi. Experiments were carried out randomly with 3 replications to overcome the obstacles that occurred during the machining process. The research results show that to reduce the alteration of the response simultaneously, the cutting speed has a value of 61.98%, the depth of feed has a value of 16.28%. And eating motion has the smallest value of -12.45%. To obtain a minimum workpiece surface roughness on AISI 4340 steel with the MORI SEIKI SL-25 CNC machining process, the cutting speed is set at 130 m/min, the feed depth is set at 1.0 mm and the feed motion is set at 0.55 mm/put.

Abstract

Resam itself is a wild plant that commonly grows around shady and moist cliffs, resam plants can be found in almost all tropical and subtropical regions in Asia. Previous research using resam fibers as composite reinforcement materials showed that resam fibers have an effect on tensile strength and impact strength based on NaOH treatment. Therefore, the purpose of this study is to utilize resam fiber as a composite reinforcement material. Not only resam fiber, this study also utilizes shaved wood powder / itchy field as a composite strengthening added material. The method used in this study is a factorial experimental method, where the parameters used are variants of fiber volume fraction and wood powder. The volume fraction variant used is 8% fiber: 4% wood powder, 6% fiber: 6% wood powder, 4% fiber: 8% wood powder. The results of tensile testing showed the highest tensile strength was located at a percentage of 8% fiber: 4% of wood powder was 14.5 MPa and the lowest tensile strength was located at 4% of fiber: 8% of wood powder was 12.64 MPa. While the results of impact testing showed the highest impact strength was at a percentage of 8% fiber: 4% wood powder which is 35.52328 Kg /² and the lowest impact strength was located at a percentage of 4% fiber : 8% wood powder which is 23.4041 Kg / mm ².
