Design and Fabrication of Computerized Numerical Control Based Pneumatic Punching Machine
Publication Date : 05/07/2019
Punching has a wide usage in industries. Holes need to be punched in sheets; pipes of a various materials for assembly purpose are demanded. Here, the promotion of holes in various materials is carried by applying pneumatic force which was fully automated by computerized numerical control. The pressure is required up to 10bar to punch the sheet metal. Punching movement is controlled by G-codes & M-codes through Master Cam software for various position of pneumatic cylinder. The circuit is designed and analysed through Multisim software. The movement of chain & sprocket and pneumatic cylinder were gets time delayed its working by Arduino circuit board. The coding for time delay is coded by Arduino software. The total punching force required for punch the different material is analyzed and evaluated. Then, conclude which one is suitable for punching the material in easily and non-broke able condition.
