Accuracy vs. Repeatability

All Boss fiber laser cutters have an accuracy of 0.004″ or better, which far exceeds most requirements. Often fiber cutter manufacturers use use only a single axis positioning accuracy for their overall rating. The machine’s overall accuracy is affected by the other axis as well as the power source, optics, and cutting head. Quality components such as Yaskawa’ Sigma7 servo motors with ball screw drive and dual HIWINN rails make the Boss AccuCUT the most precise fiber cutter in its class.

Accuracy: Maximum deviation from the input on the initial pass.

Repeatability: Maximum deviation of additional passes from the initial.

Accuracy and Repeatability Models

The green dot represents the initial cycle and the red dots represent additional passes. For comparison only, not meant to represent typical results.

High Accuracy and High Repeatability

The initial position is accurate and the machine holds a tight pattern on repeat passes.

Low Accuracy with High Repeatability

Although the initial position may be off from the target, additional passes deviate little from the initial position.

High Accuracy with Low Repeatability

The initial location is accurate, but the machine cannot return to the same location on repeat passes.

Low Accuracy and Low Repeatability

The initial position is inaccurate, and the machine cannot return to the same position on repeat passes.
