Overview
Achievable workpiece accuracies in three dimensions
EA
+ M
The reference values are based on detailed experiments where, among
other things, such sample parts were produced on a DMU 65: with different
T-type rotary tables (TF and T1), with and without WMS, with and without
compensation. Depending on the machine's accuracy and the conditions listed
below, the following workpiece accuracies are possible:
