Abstract

Clamping in workshop practice usually use tools and holding devices such as a vice to clamp the workpiece. Hence, thin wall components have always been a challenging problem due to the low stiffness of work parts during machining. Therefore, the right selection of vice is important to obtain the desired performance due to machining. In this study aims to relate the research literature review by providing the new experimental results based on a measurement of the process consist of the response of machining parameters in terms of thrust force and surface roughness. Experiments were carried out on acrylic towards endmill machining with chosen cutting parameters. Furthermore, the analysis was carried out in achieving thrust force by a dynamometer and good surface roughness for the influence of process parameters on the suction vacuum clamp during machining. Cutting tool 2 flutes of 3mm diameter were chosen in these experiments to study the superior surface quality to the acrylic material at the velocity of cutting tool speed during machining in surface roughness analysis. The result shows that vacuum clamping has better surface roughness result with the average of surface analysis is 0.585μm for continuously pressure (CP) method and 0.663μm for remain pressure (RP) method. As a conclusion, all the various result and data is taken from experiments conducted against vacuum clamping to the machining performances
