Ballbar Analysis

Ballbar Analysis of CNC Machines

Ballbar analysis measures contouring errors in machine centers that are only apparent when the machine is in motion by converting data into a plot, which displays the true movement of the machine. From this recorded movement, the actual tolerance of the machine can be calculated and compared to the acceptable part tolerance. This value will drive appropriate corrective action plans.

Ballbar data will quantify faults in the machine center such as; servo mismatch, stick-slip error, straightness of the axes, lateral play, backlash, reversal spikes, circularity error, scale and machine geometry. Each of the above conditions can be trended over time.

Your custom ATS report will include a plot of the machine’s true movement, table listing of quantifiable errors, and recommendation on how to improve the machine performance. Severity assignments are based on the difference between the actual machine performance and the required part tolerance.
