The article states that by giving programmers the ability to simulate everything about the machining process\u2014the tool holders, spindles and turrets, the constantly changing work piece and the cutting tools moving around and through it\u2014software developers are making their virtual worlds into highly accurate predictors of everything that will occur once that green button does get pushed.They conclude that if your shop isn\u2019t using toolpath simulation software, then you\u2019re wasting valuable production time and putting expensive machine tools and safety record at risk.<\/P><\/p>\n
Siemens\u2019 perspective figured prominently in the story about the importance of toolpath simulation sofware. You can read the quotes from Vynce Paradise, Siemens\u2019 Senior Director for Advanced Part Manufacturing, below.<\/P><\/p>\n
The G-code driven simulation in NX CAM from Siemen<\/A>s uses the same NC programs that drive machine tools. The highly-accurate simulation helps companies eliminate failures, improve part quality, and increase machine uptime, according to Siemens.<\/EM><\/P><\/p>\n <\/EM>Straddling the fence between standalone and integrated simulation is Siemens PLM Software Inc.<\/A> (Plano, TX). But as Siemens\u2019 Senior Director for Advanced Part Manufacturing Vynce Paradise explained, the company decided along the way to develop its own spin on simulation, one that is an integral part of its NX CAM software<\/A>.<\/EM><\/P><\/p>\n \u201cThere are many good CAM systems out there and all offer some level of toolpath simulation, but it\u2019s important to recognize that there are multiple levels available,\u201d he said. \u201cThere\u2019s the basic simulation where you can see the stock model, the cutting tool, and maybe the tool holder, each moving relative to one another. We call that toolpath verification, and while useful, it\u2019s just a starting point.\u201d<\/EM><\/P><\/p>\n Take that one step further and you have true machine simulation, the \u201cdigital twin\u201d. \u201cThis is what we\u2019re focusing on today,\u201d Paradise pointed out. \u201cIt goes beyond the basics just described to include all aspects of the machining setup, each with its own kinetics and relative movement. Many CAM systems today show this, but what\u2019s different about ours is that we\u2019re posting NC code on the fly and using it for simulation in NX CAM,<\/A> providing a \u2018best of both worlds\u2019 solution.\u201d<\/EM><\/P><\/p>\n Paradise offered the following analogy: If you want to become an airline pilot, would you rather learn in a flight simulator that uses generic flight simulation software or in one that more closely replicates the control environment of the actual plane? \u201cCAM-integrated simulation using the actual G-code is very similar to the latter and remains the most complete way to replicate what\u2019s going to happen during the machining process.\u201d<\/EM><\/P><\/p>\n Click on this link<\/A> to view the entire article published on AdvancedManufacturing.org.<\/EM><\/P><\/p>\n
