Development of a wood carving machine to create work pieces in the Tai Loei style

Abstract

This research proposes development of a wood carving machine to create work pieces in the Tai Loei style compare to human skills in terms of time and accuracy. We use control board for stepper motor 2 phase NEMA17, 1.8degree, permanent magnet: stepper motor for x and y axis. The rotation of the stepping motor that will rotate in 1 circle has 360 degree and the motor rotates 1 step, equal to 1.8 degree/1 step. For calculate rotation value in 1 spin cycle in order to find the correct pulse signal: When input the values into the controller to get the correct rotation distance call that value step/mm. It can be calculated from the following information: Number of pulses in 1 motor rotation equal to 360 degree divided by 1.8 degree so that steps/revolution is 200 step/mm. We set the micro step form stepper motor control board is 32 step/mm. By experimenting each of the X axis and the Y axis by the experimental value of 50 and 100 millimeters , Workpiece milling distance 50 mm. measuring distance in X axis 49.8 mm. Error 0.2 mm. Y axis 49.8 mm. Error 0.2 mm. accuracy is 99.6%. Workpiece distance 100 mm. Measuring distance in X axis 99.6 mm. Error 0.4 mm. measuring distance in Y axis 99.6 mm. Error 0.4 mm. accuracy is 99.6%. The result of development of a wood carving machine to create work pieces in the Tai Loei style compare to human skills in terms of time and accuracy, the operation of the machine is accurate about 99.6% and  the image obtained has a symmetry and image scale is not distorted.
