<![CDATA[This research was conducted to find out the influence of the implementationof CAD/CAM for CNC milling process to the surface roughness andprecision. Specimens were made by using seven types of cutting process.There are face milling, pocket milling, profile milling, slot milling, drilling,thread milling, and surface contouring. The results showed that theimplementation of CAD/CAM with a variation of the cutting processproduces roughness value which is lower than without the implementation ofCAD/CAM. The surface roughness values for each of the cutting processwere face milling process (0.5028 μm; 0.5132 μm), slot milling (0.664 μm;0.6556 μm), profile milling (1.282 μm; 1.3128 μm), pocket milling (1.3852μm; 1.4856 μm) and drilling process (1.9944 μm; 2.1136 μm). The averagevalue of the dimensions from the measurement showed the differencebetween the results of the implementation of CAD/CAM and without theimplementation of CAD/CAM. The percentage difference in the length andwidth were respectively 0.037%; 0.059% for profile milling; 0.039%;0.061% for pocket milling; and 0.151%; 0.317% for drilling. Statistical useof the implementation of CAD/CAM does not significantly affect the value ofthe surface roughness but it has a significant influence on the precision ofthe product with a 95% precision level.]]>
