ABSTRACT:
A device which substantially compensates for the expansion or contraction of a machining apparatus to varying temperatures in and among the components of the machining apparatus links two axes of movement of the machining apparatus by providing a measurement axis defined by the intersection of a first vertical plane passing through the cutting tip of a cutting tool and a second vertical plane passing through the workface of a workpiece to be machined, and associating one end of a temperature-insensitive member with this measurement axis, the other end of the temperature-insensitive member being in the same vertical plane as a reference point which remains stationary with respect to the measurement axis regardless of the thermal growth of the components of the machining apparatus.
