A new machining process model that explicitly includes the effects of the edge hone is presented. A force balance is conducted on the lower boundary of the deformation zone leading to a machining force model. The machining force components are an explicit function of the edge radius and shear angle. An increase in edge radius leads to not only increased(More)
A new class of machine codes for the specification of Pythagorean-hodograph (PH) curve tool paths, and associated feedrate functions, is proposed. The PH curves are a special family of free-form curves, compatible with the Bézier/B-spline representations of CAD systems, that are amenable to real-time interpolation at constant or variable feedrate directly(More)
3.2 Validation on Compressor Disc. Effect of optimal machining parameters on dimensional instability in compressor discs is shown in Fig. 1. The locating diameter 400 ͑ϩ0.02/0.00͒ mm was machined using the optimal machining parameters derived for 11–20 micron tolerance group. The diameter maintained at 400 ͑ϩ0.010/0.00͒ mm during machining has changed to(More)
