Accuracy and precision of machine axis movement are paramount in achieving the tolerances and surface finishes required in today’s part-production environment. Part dimensioning can often require grinding operations, where vibration, heat generation and abrasive particle creation are concerns in maintaining positional and speed accuracy. Selection of the axis translation mechanism will determine the level of accuracy possible along with the cost of machine ownership. For workpiece or tooling movement accuracy, there are three aspects of the machine design to consider: the mechanical components, the command and control of the movement (control boards and servo loop), and the translation mechanism (linear motor or rotary motor and ball screw). This article is focused on one aspect of translation, specifically the force generated by linear electric motors.
