“…Namely, the predicted surface roughness Ra or Rz is the product of the calculated vibration amplitude R (13) for turning with a certain Comparing the results plotted in Figures 7 and 8, it is concluded that the circular velocity has a smaller influence on the surface roughness than the feed ratio. The same result is obtained by analyzing ( 25) and (26). Namely, it is seen that the force terms connected with feed ratio are more significant than those with circular velocity.…”

“…Upadhyay et al [1] and González-Laguna, A. et al [24] extended the conclusion by analyzing the measured vibration signals. Based on the measured results it is concluded that the vibration properties, but also the roughness of the surface and the wear in turning [25], depend on the cutting tool parameters [26] and also on cutting parameters [27] e.g., speed, depth of cut, lubrication conditions and feed rate [12]. In addition, it is seen that based on the measured vibration properties of the system the prediction of the surface roughness is possible.…”

This paper deals with prediction of the roughness of a cutting surface in the turning process, applying the vibration data of the system. A new type of dynamic model for a workpiece-cutting tool system, appropriate for vibration simulation, is developed. The workpiece is modelled as a mass-spring system with nonlinear elastic property. The cutting tool acts on the workpiece with the cutting force which causes strong in-plane vibration. Based on the experimentally measured values, the cutting force is analytically described as the function of feed ratio and cutting speed. The mathematical model of the vibrating system is a non-homogenous strong nonlinear differential equation with complex function. A new approximate solution for the nonlinear equation is derived and analytic description of vibration is obtained. The solution depends on parameters of the excitation force, velocity of rotation and nonlinear properties of the system. Increasing the feed ratio at a constant velocity of the working piece, the frequency of vibration decreases and the amplitude of vibration increases; increasing the velocity of working piece for constant feed ratio causes an increase of the frequency and a decrease of the amplitude of vibration. Experiments demonstrate that the analytical solution of the nonlinear vibration model in turning process is in direct correlation with the cutting surface roughness. The predicted surface roughness is approximately (1–2) × 10−3 times smaller than the amplitude of vibration of the nonlinear model considered in this paper.

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.

“…The factors affecting surface roughness are cutting tool geometry, depth of cut, cutting velocity, feed rate, work material chemical composition, and rigidity of machine tool [7]. During the machining process, if the tool material and cutting parameters are not selected properly then the cutting tool wears out quickly or experiences catastrophic failure.…”
