Regular performance tests

The QC10 ballbar can evaluate machine tool performance quickly and simply, with a fully automated test procedure. In only 10 minutes*, the positional data obtained can identify and quantify a wide variety of errors on a machine, from machine geometry to controller related problems. Maintenance can then be quickly focused on the identified problem areas, adjustments made and the results confirmed by performing a further QC10 ballbar test or ML10 laser measurement. Similarly, the MCG can establish a benchmark volumetric accuracy value for CMMs from which trends can be ascertained at regular intervals. *Based on typical feedrates and test radius 3. Regularly re-check machine Re-check the machine with the QC10 ballbar or MCG at regular weekly or monthly intervals, following machine relocation or machine crash, or when parts begin to drift from tolerance.Regular pre-planned checks enable a machine’s performance to be charted over time and future accuracy problems to be intelligently predicted through trend analysis. Using Ballbar 5 HPS software users can review a series of tests via the machine history function. 5. Repair, and recalibrate with a laser4. Pinpoint problem areas If overall machine accuracy falls below an acceptable level, use the QC10 diagnostic software to analyse and pinpoint problem areas. On CMMs, it is advisable to perform a laser test to identify the specific location of an error. After maintenance work, the machine can be recalibrated using the ML10 laser measurement system. At this point it is possible to refer back to stage 2 to repeat the cycle.
