This article shows the regularities of formation relationship between parameters roughness treated surface under conditions processing with a tool made superhard materials. Features ratio height Rmax/Ra for diamond-abrasive are shown. In general, in relation to we have kind "roughness arc", when first normal untreated rough source it is close 4, then abrasive-diamond treatment this raises 6 and...

The mathematical model was compiled for the studies of the dynamics of an abrasive processing in a magnetic field. An analytical solution of its nonlinear part was found synthesizing harmonic balance method and computer algebra technique. Solutions of the linear part were obtained by the traditional numerical techniques. The numeric investigation of process dynamic features was fulfilled, regim...

Investment castings (usually involving ceramic based shells) have traditionally been separated from the mould tree using an abrasive cutting operation. While material removal rates are relatively high, the process unfortunately suffers from poor accuracy control that often necessitates further finishing operations. Following an overview of key considerations in investment casting including tree...
