If you have a machine with an automatic tool changer this wouldn’t be a problem, but most hobby machines don’t, so you will have to plan ahead. If you set your Z axis datum on the top of the stock, as soon as you run the roughing pass this reference face will disappear leaving you no way to set the Z datum for your finishing tools.

Z Axis Reference FaceĪn issue you can have when milling a free form 3D file is your Z axis face being milled away with the roughing toolpath. The excess stock gave me enough room for error for keeping the finished shape within the piece of rough cut wood I used. I then used a pointed tool to pick up the pencil cross to establish my X and Y axis datums. Set your X and Y Axis Datumsįor my part, because I had enough excess stock, I only needed to mark the center of the part with pencil lines. You will also need to extend your cutters out enough to clear the top of the part. Using a vise eliminates this issue, you just have to make sure the stock is tall enough so that the tools don’t hit the top of the vise jaws. You don’t want any clamps where the tool will go. Once the program is ready to run you will need to setup your cnc machine. This should confirm that it posted without any errors. Once you have your G-code, load it into your g-code software.

If you are unsure, the software usually does an ok job of setting values, so you can leave most options as they are. Testing is the key to learning, so make adjustments and test. This toolpath is ideal for finishing steep walls so I used it to finish the outside of the model first. I used three finishing strategies for my statue head. Again, test and try different options, you can’t break a virtual machine! The ‘rest’ function is designed to solve this sort of issue but is beyond the scope of this article, that’s not to say it’s complicated though. You may also need to do a semi finishing tool path with a larger tool tool first to remove larger areas of remaining stock that were missed in the roughing process. The Finishing Toolpathĭepending on the shape of your 3D model this may be more than one toolpath. This will help you decide what you need to adjust to get your desired result. When you are trying different strategies remember to use the simulate function to check what the cutter will actually do. Just remember that a smaller depth of cut will remove more material on a model that has a lot of variations in height and surface features.Īgain test and try different approaches to see what works best. In this situation 3D adaptive clearing works just fine for the model I am using. No Cam software is perfect, so don’t try and fight it, sometimes you will have to find a workaround to get the result you need. If your 3D model has a concave area you may have to test the pocket options.ĭon’t try and find one strategy to rough the whole part if using two or three works better. This is the easiest choice and usually comes down to 2D adaptive or 3D adaptive clearing.

There is not always a set process when deciding on a machining strategy it is highly dependant on the shape of the model.Ī lot of trial and error will need to be applied when you are still learning which will reduce to a small amount of testing when you are more familiar with the software.

Now you can start the interesting (fun) part of the Cam process, deciding how to machine the part. It only has to be approximate, but it would be preferable to make it slightly bigger than smaller. In the stock tab you should adjust the amount of stock to match the physical size of the material you are using.
