The ANCA CPX in-process OD measurement system.

In-Process OD Measurement for Tool Grinding

July 27, 2022
Permanently mounted system uses SPC to measure tool blanks’ outside diameters in batch processing of tool blanks, based on pre-set tolerances.

ANCA, the tool-grinding machine specialist, will present the CPX in-process OD measurement system at IMTS 2022 – booth 237406 – a quality control system that monitors and controls the outside diameter of ground blanks in a batch production process.

Batch grinding on with high material removal rates and to tight tolerances is a basic function of the ANCA CPX machine; the OD measurement system takes it further by utilizing the Statistical Process Control (SPC) feature that comes standard with the OD measurement software. SPC is user-defined, and the tolerances along with the Cp and CpK values are constantly monitored, controlled, and reported to the user.

The OD measurement system is permanently mounted inside the machine and only called upon when required, based on the set tolerances and the frequency of measurement, an accurate in-process measurement and compensation is applied to maintain the blank OD to the nominal diameter.

The system is flexible with the ability to handle multiple diameters in one setup, making it perfect for complex blank geometries/shapes and longer batch runs.
