The QC20-W ball bar features a linear sensor and Bluetooth wireless technology for greater ease of use and enhanced durability, the company says. The design also allows testing in three orthogonal planes through a single reference point. A single hardware setup enables quicker testing and the ability to produce a representative volumetric measurement of positioning accuracy. The ball bar retains the principle of a simple CNC circular program and powerful software. Together, these features enable the ball bar to diagnose and quantify machine positioning errors, including servo mismatch, stick-slip, backlash, repeatability, scale mismatch and geometry, and to provide an overall circularity error value.
