CNC Programming
  • How to choose the best CNC programming software for your PCNC mill.

    While CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing) software is not necessary to run a Tormach PCNC, it will greatly expand what you can do with a CNC mill. PCNC mills will work with any CAD/CAM system that can output industry standard G-code; however, gracefully machined curves and contoured surfaces are essentially impossible to program without the aid of a capable CAD/CAM system.

    Choosing a CAD/CAM system can be overwhelming if you are new to these types of software programs. Tormach is a proud reseller of several CAD/CAM software products that we think are well-matched for use with a PCNC mill:

    • IronCAD – The fastest way to 3D.* IronCAD's unique design interface makes it easy to create 3D models quickly and easily.
    • SprutCAM – Serious CAM, Exceptional Value.* SprutCAM is an affordable full-featured CAM program for professional shops that offers over 30 programming strategies. Hundreds of options are available for complete tool path control.

    *Special Pricing Available for Tormach PCNC Owners

    Beyond the products listed above, Tormach PCNC mills can work with virtually any CAD/CAM system. Whether you choose one of our CAD/CAM offerings or not, it is important to choose software that will meet your needs in regards to functionality, affordability, and usability.

  • CNC Programming FAQ

    1. What is a post processor?

      A post processor is a component of your CAM software and is the final step in the CAD/CAM process to create G-code that is useable with a CNC machine.  The post processor converts the tool paths designed in CAM into G Code and is generally unique to the CNC machine and/or controller being used.  Postprocessors are generally provided by the CAM company, often as an ala carte or value-added service.

    2. What is a Programming Wizard?

      A Programming Wizard is a tool for creating simple G-code programs via parameterized inputs.  These inputs define both the geometry parameters and process parameters. For example, a programming wizard for a creating a bolt circle needs geometry parameters (i.e., number of holes, circle diameter, etc.) and process parameters (i.e., spindle RPM, feed rate, etc.).

    3. What is G-Code?

      G-code is the programming language used by almost all CNC machines.  A G-code program is a series of sequential instructions that tell a CNC machine where to move, how fast to go, and what path to take. Simple G-code programs can be hand-coded, but more complex part programs are often generated by CAD/CAM.

    4. Do I need CAD/CAM to operate a CNC mill?

      Not necessarily. Simple part programs can be hand-coded by directly typing G-code. This can be done by either using an ASCII text editor (such as Microsoft Notepad), or by typing G-code directly into the controller via the MDI (Manual Data Input) function.  Programming Wizards are also available and can be used to create G-codes for many typical part features without the need for a full CAD/CAM solution.

    5. What is CAD/CAM?

      CAD/CAM refers to a class of software tools that are used to aid in design and manufacturing applications that use CNC (Computer Numeric Control) technology. In the case of CNC Machining, CAD (Computer-Aided Design) is used to create a digital model of the part. In turn, this model becomes the input to CAM (Computer-Aided Manufacturing), which is used to create the instructions for the cutting the part. These instructions are known as tool paths.
