How to use MEY effectively

Ramping/Helical milling

  • Ramping angle is recommended to be 8˚ or under.

Sinking depth per revolution when helical milling

should be 1/2DC or under.

  • Use compressed air during machining.

8˚ or under

øDS (How to find diameter of trajectory of tool's center line) øDS = øDh - DC h How to find h h =πXøDS X tan α (α should be 8˚ or under )

Shouldering

  • Tools with 1mm larger cutting diameter than shank diameter are available. High wall shouldering is possible.
