This article refers to today's most used, most productive and most reliable method of programming - programming using CAD / CAM systems. Today, different programming methods are used: Manual, programming in operation, programming using programming languages (here we primarily mean other programming languages such as APT, AUTOPRIT, AUTOPROGRAMER, COMPACT II, etc.) and programming using CAD / CAM systems. This unique program, which controls almost all CNC machines, is called the NC program or better known G-code (This name was given because most functions in this programming language refer to defining the geometry of the part being processed - G functions). Numerous, letters and other symbols arranged according to certain rules and coded in the required form make up the program, necessary for providing the intended functions of the working bodies of the machine. Just assume you’ll make a few mistakes along the way (i.e don’t start with that expensive plywood sheet), and you should be good.For CNC (Computer Numerically Controlled) machine tools or CNC systems, all information for processing work subject is obtained in the form of numerous, letters and other symbols. ![]() The default value works fine, just be aware if you start to mess with it.īasically, it’s a learning curve, just like everything else. If that happens on the left edge of the machine, the chains have the worst angles to keep that from happening. For example, a clockwise bit cutting downwards (towards the floor on the Maslow) will tend to move to the right (the bit “rolls” on the material). The other operations worked fine, you just have to keep in mind what direction your bit rotates in, and how that affects the cutting forces. I just gave up and used actual pockets instead. I understand that Adaptive clearing, 2D Contouring and 2D pocket are milling operations, why did you have trouble with them?Īdaptative clearing never recognized my pockets properly. When you mentioned the Stock to leave setting are you talking about Fusion assuming you’ll be changing bits to do a final finishing pass, therefore it leaves behind a final layer rather then cutting through the entire thickness? I understand that people much smarter then me use these programs but Fusion seems to do a good job of laying out the tools and operations that are more commonly used but allows advanced settings and tools to be accessed if you know what you are doing. ![]() I am attempting to CNC and Arcade Cabinet that I designed so having accurate cuts within reason is important, should I abandon Fusion and use something else? It attracted me because modeling and designing in it seemed more intuitive, fusion didn’t seem to suffer from the too many features syndrome that many of CAD software seem to have. Please excuse my noob questions but though I understand that Adaptive clearing, 2D Contouring and 2D pocket are milling operations, why did you have trouble with them? Is it related to having a manual Z-Axis? I have Maslows Z-Axis so would that make my results better? Is this just a fusion thing? Why is this process so weird, I would think flattening out components would be standard considering most CNCs and Milling machines work on a flat surface, with the exceptions being 3D mills. it basically moved the components everywhere randomly and would have taken hours to put it all back. The first video you listed is the one I watched, I followed the steps and while it does allow me to flatten everything, it seemed to effect my assembled model to the point where I had to undo everything to get it all back to normal. Thanks for the response, The post you listed is the one I found myself, how would I go about getting that to work with Fusion, do I just put it in a folder? Which one? Also look into the “stock to leave” values, they tend to not be 0 (expecting another finishing operation). Other than that, look into “conventional milling” vs “climb milling”, climb seems better for pockets, but I’ve had horrible failures with it for contours (the bit started to “walk” through my material during a downward move on the left of the machine). I customized the default values quite a bit, but that was mostly to get it to generate as few Z-axis moves as possible, as my Z-axis is manual for now. ![]() I also haven’t had much success with the “adaptive clearing” operation, I usually keep to “2d contour” and “2d pocket”. There is a video tutorial on Youtube, it’s either this one: or this one: It works pretty well in my experience.įor flattening, I group my parts into a “3d” component and then copy them over to a “flat” component. ![]()
