Abstract:The 2D kinetics of the workpiece during barrel finishing operation is studied. A particle image tracking technique was applied to a transparent thin barrel in order to acquire the position of the part within granular flow in rolling regime. The use of industrial near shape media leads to an intrinsic difficulty to trace the part position. The achieved trajectories permit to calculate the active working time, part density distribution, the media velocity gradient and the workpiece to media velocity gradient. These information are useful to calculate the total sliding and to get information about strain stress over part in order to investigate operation efficiency.

- International Journal of Machining and Machinabilty of Materials is a refereed international publication in the field of machining and machinability of materials. Machining science and technology is an important subject with application in several industries. Parts manufactured by other processes often require further operations before the product is ready for application. Machining is the broad term used to describe removal of material from a workpiece, and covers chip formation operations - turning, milling, drilling and grinding, for example. Machining processes can be applied to work metallic and non metallic materials such as polymers, wood, ceramics, composites and special materials. Today, in modern manufacturing engineering, there has been strong renewed interest in high efficiency machining.
