Presented is an experimental investigation of the machining characteristics and the effect of wire electrical discharge machine (WEDM) process parameters during machining of Al/ZrO2(p) particulate reinforced metal matrix composite (PRMMC). Experiments are carried out to investigate the effects of input parameters such as dielectric conductivity, pulse width, time between pulses, maximum feed ra...

PVC frame cutting process by guillotine is a common method that attracted attention of car parts and PVC decorating furniture producers. In this paper, the effects of main parameters such as cutting speed, lubricants and cutting frame holder pressure force on PVC frame section surface smoothness is investigated by experimental methods on a specified PVC frame sample and then by FEM simulation u...

turning of hardened steels using a single point cutting tool has replaced the cylindrical grinding now as it offers attractive benefits in terms of lower equipment costs, shorter set up time, fewer process setups, higher material removal rate, better surface quality and elimination of cutting fluids compared to cylindrical grinding. in order to obtain desired surface quality by machining, prope...

In recent years, more and researches have been carried out on the erosion mechanism of abrasive particles target materials in waterjet cutting process. However, effect material property factors damage is rarely studied systematically. this work, a 3D smoothed particle hydrodynamics-finite elements model established for simulation. The controlled variable method used to study how each factor aff...

For the machining of long and narrow surfaces when processing multiple pieces, planing technology is used, productivity which can be higher than that milling, although it relatively slow machining. The article aims to study degree influence geometry tool (the angle cutting-edge inclination tool-orthogonal rake), as well cutting conditions (cutting depth speed) on chip characteristics (temperatu...

Can we flatten the surface of any 3-dimensional polyhedron P without cutting or stretching? Such continuous flat folding motions are known when P is convex, but the question remains open for nonconvex polyhedra. In this paper, we give a continuous flat folding motion when the polyhedron P is an orthogonal polyhedron, i.e., when every face is orthogonal to a coordinate axis (x, y, or z). More ge...
