What is a Machine Controller?

Machine control, unlike a more specific type of controller such as a motion controller, refers to the control of an entire stand-alone machine such as a CNC machine, packaging machine, or even a vending machine. The machine controller's primary operations include scanning I/O, updating output and process control. After an initialization phase, the controller will continuously read inputs, calculate control parameters for the machine process using application-specific logic based on the input data, and then update outputs to the machine. If the controller is turned off, some shutdown process may be completed.

  • Autodesk provides real-time DFM for plastic part design

    There’s a lot of benefit to be had by doing manufacturability analysis (DFM, Design for Manufacturing) early in the design process, rather than waiting until later, when design changes are far more expensive. A couple of years ago, Autodesk Labs previewed a product, Project Krypton, which ran inside of 3D CAD programs (including Autodesk Inventor, DS SolidWorks, and PTC [...]
