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. as a percentage was 1.11. The percentage of errors size 36 cm. as a percentage was 0.28 percent. The percentage of errors size 57 cm. as a percentage was 0.00 percent. The Tolerances of the foam cutting is acceptable. The size of the foam with precision the most.
