Clamping in tool room usually uses tools and holding devices such as vise to clamp workpieces. However, conventional clamping device such as vise is time consuming, expensive and can not hold thin workpiece. Therefore, this project presents the design and development of portable vacuum clamping (Pvac CLAMP) for tool room to overcome those limitations. To design and develop Pvac CLAMP, the machines used in the process are milling machine and drilling machine. After Pvac CLAMP had been developed, a test were carried on the Pvac CLAMP. The test was surface roughness measurement. The result shows that Pvac CLAMP has better surface roughness than theconventional vise about 40% reduction.
