To test the movement axis X and axes Y configure of the program ready-made Mach3. settings defined Step per 100 set Velocity defined 1400 and defined Acceleration 1 400. by The test configure in the program Mach3. In term of X axis. 5 the value. found that the Value error of the cutting machine foam equals 0.49 centimeter. Percentage error of 0.72 percent. From the test by Break the foam cutting out as 3 size. font ก Was found that The foam cutting of each size. The percentage of errors size 18 cm Precision of 96.78 percent size 36 cm accuracy was 87.08 percent. The size 57 cm accuracy was 68.70 percent. The accuracy of the foam cutting is acceptable. The size of the foam with precision the most.
