Basic Class

Best for students with no prior CNC experience.

This class will cover an introduction to CNC’s.  We will cover the environmental and mechanical components of the machine along with basic servo theory. 

We will disassemble and reassemble the simulator.  While doing this, we will look at the major components and discuss how their failure will impact the machine.  We will discuss slideways, ballscrews, tool changers, lubrication systems and bearings.  We will also look at the high voltage components such as motor contactors, relays, transformers and power supplies.  We will go through the proper procedure to check a motor and cable for shorts.

Basic Class Available Dates
  • 12/5 to 12/7: Louisville, KY
  • 12/12 to 12/14: Louisville, KY

    Intermediate Class

    Best for students with prior experience in the mechanical aspects of CNC.

    This class will cover the interface between the CNC, Ladder logic and machine tool.  We will discuss how signals are sent from the machine side, processed in the ladder logic, and then sent to the CNC.  We will cover a number of diagnostic screens that are used to troubleshoot the machine.  These will include the status screen, trace function, operator history, FSSB and alarm history.  We will also be troubleshooting a number of servo related alarms.  Backlash compensation, grid shift and reference return procedures will be covered.

      Advanced Class

      Best for students looking looking to go from “Pretty Good” to “Expert”

      This class will build upon the information learned in the intermediate class.  Here we will be taking a detailed look at the CNC to PMC addresses.  This is where you will learn to troubleshoot issues such as an intermittent feed hold, axis interlock, M-code failures and others.  

      We will look closely at a number of CNC parameters and diagnostics.  We will demonstrate how to enable and disable scale feedback systems.  Multiple labs using ladder logic function statements will provide the students with hands on troubleshooting techniques.

        Custom Class

        Covers potential issues on machines in your facility

        This is an advanced class that uses the ladder logic and I/O configuration from machines used on your shop floor.  We will use this information to closely examine how your equipment is interfaced and how to go about troubleshooting it.  I will modify the schematics with pictures to help identify the primary components along with troubleshooting notes.  Please contact us for additional information regarding the types of controls that this can be used with and necessary documentation.
