Temp. compensated NC machine system - has correcting programme based upon temp. expansion characteristic

摘要

High performance numerically controlled machine tools exhibit errors due to thermal expansion. The system is modified to include a compensation for such temperature effects. The particular material being machined has a defined temperature-expansion characteristic that is entered into the main store of the control system computer. In operation the correction programme utilises the stored data for specific temperature conditions. The system is intended particular for lathes.
