This study investigated the wear phenomena of chamfered acetabular cup liners. The liners have three parameters at the lengthened rim: the length of the elongation, the depth of the cup and the chamfer angle. Using published wear volume equations for cylindrically elongated liners, this study analysed the volume of the chamfer to obtain the exact(More)
Nesting is primarily composed of two processes: One is the determination of permutation; another is the placement for the pieces unto the sheet. These two processes determine the quality for nesting. If the permutation is right and placement also can satisfy the requirements, then we can locate the proper solution  or the optimum one; but most(More)
The objective of two-dimensional optimal nesting problem is to place the same or different pieces of the fixed quantity on the sheet in this paper. What we want to do is increase the rate of utility and decrease the waste of panel. Generally, determine the quality of the nesting results; it can briefly be divided into two factors: placement algorithm and(More)
Due to the rotary axes of the machine, the tool path between two blocks in the NC program will drive the pivot move non-linearly relative to the workpiece, reducing the accuracy of the tool path. Linearization of the tool path in the postprocessor will solve the problem. An algorithm will be proposed to modify the exact inverse kinematics in order to give(More)
