1) Tooling marks are formed on the OD of the part due to rotation of the part inside fixture during machining running time.|2) Clamping force was not uniformly distributed on all the parts.|3) 4 parts are loaded per setup and according to the fixture design all the four parts are clamped by using a clamp made of single material (Refer MPS for more details) because of which if the variation of the OD between four parts are greater than .01mm the clamping force will not be equal on all the parts.
