14.4.9 Useful data of the function "temperature compensation"
Function number 9
Temperature compensation is required if the thermal expansion of certain machine parts
causes an offset between the measuring system and the tool or workpiece.
There are two types of compensation, which can be used individually or together.
In position-dependent temperature compensation, the compensation value is directly
proportional to the distance between the actual value and a reference point at which no
compensation is required. The resulting error curve is defined by the reference point and its
gradient (coefficient).
In absolute temperature compensation, the deviation of the measuring system is compensated
independently of the position.
