Three-Point User Frame Setup

For a technician establishing a user frame aligned to a fixture or workpiece so taught positions can be shifted or reused across similar setups.

Basic~20 min7 steps
  1. 1

    Choose an unused user frame number

    Select a frame slot that is not already assigned to another fixture.

  2. 2

    Identify the three reference features

    Pick an origin point, a point along the desired X axis, and a point defining the XY plane on the fixture or part.

  3. 3

    Jog to the origin point

    Move the calibrated tool tip to the origin feature and record it as point one.

  4. 4

    Jog to the X-axis point

    Move along the fixture to a point that defines the positive X direction and record it as point two.

  5. 5

    Jog to the Y-axis reference point

    Move to a point that defines the XY plane orientation and record it as point three.

  6. 6

    Let the controller calculate the frame

    Confirm the prompt so the controller computes the user frame origin and orientation from the three points.

  7. 7

    Verify the frame

    Jog in the new user frame and confirm motion along each axis matches the physical fixture as expected.

Common questions

How long does it take to three-point user frame setup?
This is a basic task that takes about 20 minutes across 7 steps.
What tools do I need?
You will need Teach pendant, A pointed tool with a known, calibrated TCP.
What should I do before starting?
A tool frame with an accurate TCP is already set up. The fixture or part has clear, repeatable reference features.
What is the first step?
Choose an unused user frame number. Select a frame slot that is not already assigned to another fixture.
