Not every accuracy problem needs the same solution. This guide matches common jobs to the right type of robot calibration tools, using Dynalog's product line as the example.
Job 1: Calibrate a new or relocated cell
Tool: DynaCal. It identifies discrepancies in the robot, TCP, and fixture alignment together, then compensates for them. This is the foundation for offline programming without touch-up, robot cell cloning, and moving entire lines without re-teaching.
Job 2: Recover quickly after a crash or part swap
Tool: roPOD. It monitors the robot and its TCP during production for changes caused by wear, a crash, or component replacement. It can recover the TCP and the robot's zero-position mastering.
Job 3: Handle temperature changes
Tools: AccuBeam and DynaFlex. Both identify variation caused by ambient temperature and robot self-heating and compensate automatically. DynaFlex also provides absolute accuracy in-line, using a small-range sensor mounted on the robot.
Job 4: Guide the robot to varying parts
Tool: DynaGuide. It identifies the location of the part relative to the robot and updates the robot's user frame automatically. It suits applications needing accuracy better than 0.1 mm or involving part-to-part variation.
Job 5: Measure and verify performance
Tool: CompuGauge. It measures, visualizes, and analyzes robot performance statically and dynamically, and can perform all ISO-9283 tests as well as ANSI/RIA R15.05-1/2 tests.
How they fit together
A typical sequence runs like this:
Calibrate the cell at installation.
Verify performance with a measurement and analysis tool.
Monitor and recover during production.
Compensate for temperature where it matters.
Add guidance if your parts or fixtures vary.
Takeaway
Start with cell calibration, since everything else builds on accurate positioning. Add tools as your applications demand.
