Variable Pressure Optimization (VPO)

Variable Pressure Optimization (VPO)

  • This section defines and provides resolutions for common hardware issues for the Variable Pressure Optimization (VPO) feature on the cutting Head on the CMC models equipped with this feature.

  • Variable Pressure Optimization (VPO) Definition: The Variable Pressure Optimization (VPO) feature on the Head regulates cutting pressure when cutting Dense and Extra Dense materials on CMC Models that support this feature.

Usage:

  • Use the the Variable Pressure Optimization (VPO) feature on the Head to set the cutting pressure for:

    • Standard Matboard

    • Dense Matboard

    • Extra Dense Matboard

Connections:

  • Users can cut Dense and Extra Dense materials by adjusting the VPO air pressure.

  • The Variable Pressure Optimization (VPO) Gauge is located on the lower left front of the Head faceplate.

  • The Variable Pressure Optimization (VPO) Knob is located on the left side of the Head just underneath the faceplate.

Controlled by/Controls:

  • The Variable Pressure Optimization (VPO) feature is controlled by air pressure.

  • The Air Regulator controls the CMC’s primary Air Pressure from the Air Compressor and regulates the Clamps, Head Lift, Head Plunge, Blade Plunge, and Blade Depth.

  • The ECU/Driver Pack controls the electrical signals between the Computer, Gantry and the Control Panel on CMCs that include that feature.

  • There are Actuator Valve test buttons on the Air Valve Assembly to evaluate each of the mechanical functions for the Clamps Activation, Head Drop/Lift and the Blade Cartridge Plunge.
