The Various Effect of Various Machining Parameters on Ovality of Cylindrical Starter Motor Cover of KTM Bike

Abstract

The manufacturing refers to the processes required to convert raw material into the final product which may include casting, machining, welding, finishing, heat treatment processes and ends with final inspection to check for defects. Mostly the circular holes of hollow cylindrical components show ovality after manufacturing, exceeding tolerance values and such defect leads to poor fittings. After careful study of workpiece, clamping pressure, clamping geometry and clamping technique influence the dimensional deviations and it can be prevented by improving the production with corrective techniques. Ovality is a common term used in CNC turning, which refers to the deviation of the cross sectional shape of the workpiece from a perfect circle. It is an essential quality parameter that needs to be monitored during the manufacturing process to ensure that the final product meets the required specifications. There are various reasons why ovality occurs in CNC turning, such as tool deflection, poor workpiece support, incorrect tool geometry, and incorrect machine settings. The most common cause of ovality is tool deflection, which happens when the cutting force exceeds the strength of the tool. This results in an uneven cut and causes the workpiece to become oval shaped.
