he initial project made a 3-axis CNC milling machine, which was
improved and upgraded to 4-axis and 5-axis milling machine. Designing
parameters for 3-axis machine is better but unsuitable for 5-axis CNC milling
machine leading to the working area is narrow.
 The limitation of the working area made our team having many difficulty when
designing and programming as well as manufacturing. We must to designed
model complying with a standard of this machine.
 Manufacturing 5-D model components are not high Precision and reliability.
 A Step (0.72 degrees/pulse) is too big
 Zero set point and holder set too hard.
Development methods:
 Adjusting the machine more rigorous by digimatic indicator and Digital
Protractor.
 Improving the machine structure to make the area is more spacious
 Change step motors of A and C-axis into AC servo motor to accurately
operate, achieve higher manufacturing accuracy
 Design, manufacture more the automatical tools changing.
 Change Spindle to manufacture steel workpiece.
