Educational article: (AP306) Productive Process Pattern: Thermal correction - workpiece expansion (pdf)
Productive Process Pattern™ from the in-process control layer of the Productive Process Pyramid™. Use a spindle probe to measure the size of a reference feature in the machine environment and compare it with the known size of that feature at 20 °C. Produce and apply a scaling factor or offsets to subsequent part measurements and proceed with machining operations based on parameters corrected for thermal effects.
