Having 3-D models readily available from OEMs can reduce the time required to get CNC simulations up and running.Īccurate simulation of a machining process requires virtual 3-D model equivalents of the stock, fixtures, tools and CNC machine. Traditionally, these models were built by the end user or software supplier, but they are increasingly being offered by machine tool, fixture and cutting tool suppliers. However, 3-D simulation requires 3-D CAD models of machines, cutting tools and fixtures. Some CNC simulation software, such as VERICUT from CGTech, can also optimize NC programs to decrease machining time and produce higher quality parts. Simulation software helps eliminate or significantly reduce the need to manually or physically prove out NC programs, freeing engineers, operators and expensive machines to produce good parts. More part manufacturers are recognizing the value of CNC simulation.
