In fact the overwhelming majority read, write, or tweak programs on a regular basis. We were impressed at how many readers can write g-code programs from scratch. You should not be suprised to learn that many are quite proficient with G-Code: We recently did a survey to assess the g-code skills of our readership.

If you’re interested in CNC and machining, you should too. Why should I learn CNC Programming?Įvery CNC machinist should know g-code.

For example, you might create an initial CNC program using CAM Software and then edit the g-code from the CAM Software using G-Code Programming to make the program manufacture a part faster. Often, it’s advantageous to use multiple methods together. What are the different methods of CNC Programming?ĬNC Machines are programmed using one of three methods:
#Morbidelli post processor for feature cam how to#
In order to make a part on a CNC machine, you tell it how to make the part using a G-Code Program. It is the Lingua Franca (working language) of CNC. Some machines with proprietary formats can also run g-code. Your machine’s CNC controller probably executes g-code, although there are other possibilities–Heidenhain, Mazak, Shopbot, and others have proprietary formats. CAM programs will generate g-code from a CAD drawing, but the end result is still g-code. It’s one type of CNC programming that CNC programmers use, the other type being CAM programming. G-Code is the language used to control CNC machines.

If you’re a professional who spends most of their time doing CNC Programming, your job title is probably CNC Programmer. A CNC Program is a text file that contains g-code. There are too many variables in the real world, and standards are too restricted in scope, to achieve integration with off-the-shelf components.CNC Programming (Computer Numerical Control Programming) is the art of programming CNC machines to make parts. Standard CAM systems, standard NC machines, standard CLDATA and standard CNC post-processor vocabulary can not all be mixed together to instantly produce a working system. Wherever possible, good CNC post-processors should hide these details within. The important point to be made here is that the NC programmer should not be concerned about machine tool or machine operator idiosyncrasies that do not directly affect the production of a job. It is generally far easier to change the CNC post than it is to get a new revision of the CAM system, or a new executive revision for the NC controller. For example: pre-selecting the next tool as soon as physically possible, segmenting a tape at a tool change if the entire upcoming tool path will not fit on the current reel, selecting a spindle gear that best fits the current and subsequent speed requirements, or switching intelligently between parallel axes (Z and W) based on the types of upcoming operations and available travel limits.ĬNC Post-processors can also work around limitations and bugs in the CAM system or in the machine tool. The NC programmer uses this information to optimize the job without intervention. The best CNC post-processors maintain a global picture of the entire job at all times, using upcoming events to help make decisions about current ones. Examples include: cycles left active during a tool change (they should be temporarily cancelled), selecting an incorrect or nonexistent spindle gear range (the post-processor should select a range that supports the speed), or specifying an unavailable coolant type (the CNC post should select the next best type). There are many situations where a CNC post-processor can detect an error and correct it.

Some examples: Noting if a tool is not selected near the start of the program, warning when motions at feed rate are done with a stopped spindle, flagging long series of positioning moves, or conversely, flagging feed moves at or above the program clearance plane, or noting if diameter or length compensation switches are not changed when a tool is.īeyond simple validation comes correction. There are many simple rules that a CNC post can follow, with warning messages displayed when these rules are violated. More sophisticated CNC post-processors may validate the program before it is run by the machine tool. For example a CNC post-processor may summarize axes travels, feed and speed limits, job run-time and tool usage information, which enables better selection and scheduling of resources. CNC post-processors can do many other things besides translating CLDATA to NC machine codes.
