Improving the contouring accuracy of a HSC linear motor milling machine

Pandilov Z., Durakbasa N., Dukovski V.

Journal of Machine Engineering

2011

Vol. 11, No. 4

130--137

In recent years, instrumentation circular profile tests have been specified to assess the contouring accuracy of CNC machine tools. Such an instrumentation type test is the HEIDENHAIN grid encoder system, which is particularly appropriate for dynamic measurements, especially at high feed rates. In this paper influence of the position loop gain and sampling period on the contouring accuracy are effectively studied.
