The increasing of needs on several industrial fields such as medical, electrical and mechanical field require accurate dimensional and geometrical function and efficiency in a product, one example being the manufacture of micro-hole and micropart products. As one of micromachining processes, CNC micro blanking machine is proposed as basic technology to fabricate the component with miniaturized dimension. In this study, the validation between theoretical input on the program control and mechanical motion is conducted to significantly reduce the gap between actual carriage motion and G-Code motion. The average deviation of actual velocity on post calibration is determined to be 10.8 mm/min, while for carriage displacement for X, Y, and Z axes are -0.0191; -0,0087; and -0.0005 mm, respectively. Based on the analysis has been performed, it can be concluded that the imprecision is caused by the geometrical deviation of carriage (linear guide), so, the carriage movement is hindered by the deviation. © The Authors, published by EDP Sciences, 2018.
