Abstract
In this article, vacuum pressure for holding thin walled cylindrical object in vacuum clamping system on a computer numerical control machine (CNC) is studied. In this work, thin walled cylindrical object in vacuum clamping system is designed and different parameters for the vacuum clamping system are calculated. CNC rolling and flow farming machines are being employed for the thin wall and complicated objects. It is very challenging to make various thickness thin walled objects at high precision with help of jig and fixture at large scale. A lot of time is consumed for non-operational activities and skilled operator is required. In this work, this problem is resolved by replacing the machines built with 3-jaws hydraulic chucks with traditional made flexible clamping system. It would increase production rate and accuracy of object as compared to other conventional manufacturing processes. Designing imprecision may lead to process tolerance that caused to enhance manufacturing expenditure. In this work, optimum cutting parameters: feed rate, surface roughness and depth of cut of vacuum clamping system are deliberated. The main focus of this research is to design alternate clamping system for holding thin walled work piece with variable thickness and to save time, men power and raw material.
