Tool Orthogonal Clearance
Tool Orthogonal Clearance
What are the functions of tool orthogonal clearance?
1. Reduce the friction between cnc tools flank and work piece processing surface, affecting smooth finish.
Because the role of blunt round radius, plastic deformation, and flexibility in chip formation, it forms an elastic restore layer in transitional surface.
The smaller clearance angle, the longer contact length of layer and flank is.
This is one of the direct causes of abrasion.
In that sense, increase tool orthogonal clearance can reduce friction, improve finished surface quality and engraver tool lifetime.
2. The larger relief angle, the smaller blunt round radius, the sharper cutting edge is.
But if too big, will decrease blade strength and cooling capability, influencing machining precision.
3. Under the same wear standard, cnc cutters with big relief angle remove great metal volume using from new to blunt.
It is also one of the reasons to prolong service life of end mill bit after enlarging.
