Standards & Data Formats

Cutting Reference Point

CRP marks the intersection of critical planes at the cutting edge, serving as a reference for tool orientation and cutting angles. It is fundamental for defining rake and clearance angles.

Advantages

  • Enables precise calculation of cutting angles (e.g., GAMO, LAMS)
  • Provides a stable reference for tool geometry adjustments
  • Supports standardized definitions for cutting edge positioning

Considerations

  • Requires accurate determination of intersecting planes
  • Sensitive to insert shape and tool holder configuration
  • Must align with PCS and MCS for consistent results

CRP is a key reference point in tool design, located at the intersection of planes such as the cutting edge plane, feed plane, and rake plane. This point is used to define critical cutting angles, ensuring optimal tool performance and chip formation.

Establishing CRP accurately involves precise geometric calculations and alignment with other coordinate systems like PCS and MCS. Any deviation can lead to incorrect cutting geometry, affecting machining quality and tool life.

Integration with StOB
