Shops that want to go from programming office directly to running parts prefer G-Code Simulators. That CNC Simulator did not do its job if that can happen. If there are any problems with the geometry model, any bugs for example, the CAM Simulation may look perfect only to have the part crash on the CNC Machine. Remember, it doesn’t see the CAM package’s geometry model. This is in contrast to a g-code simulator that works from the g-code your CNC Machine will actually execute.

The problem is they work off the geometry model the CAM software uses to create toolpaths. But they have their limitations as a type of CNC Simulator. Visually, CAM Toolpath Simulation is very satisfying. They use 3D graphics and show the progress of the tool whittling away material to create a finished part. They’re included with almost every CAM software package. This kind of CNC Simulator can save a lot of time for the CNC Programmer, and also eliminate the need to tie up an expensive CNC Machine for testing.Īnother type of CNC Simulator is the CAM Toolpath Simulator. With a good simulator, “cutting air” should not be a requirement before you can run a part on a CNC Machine. The idea behind a g-code simulator is to eliminate manual testing of g-code part programs by using a simulator. We even make one ourselves– G-Wizard Editor is a G-Code Simulator. One of the most common and useful types of CNC Simulator is a G-Code Simulator. The goal of a CNC Simulator (or any other Simulator), is to solve the problems faster and easier than fooling around creating the real thing and using trial and error. As a result Simulators can solve an extremely broad range of problems. In addition, for something like a g-code simulator, the answer isn’t a single number. What’s the difference between having a formula that simply gives the answer and a simulator? Having a straight up formula is faster and easier, but often formulas don’t exist to give the answer.

That math, if the problem is well enough understood, will predict what will happen when various parameters are entered as inputs. The idea is to model the math behind whatever the problem is on the computer. Ever since computers became available, simulation became a powerful or even the preferred way of solving problems. What’s a CNC Simulator and How Can They Help?ĬNC Simulators follow in the footsteps of many other kinds of simulation.
