Tool is most appropriate for "Z-level" roughing; ramp to Depth of Cut (DOC) and clear entire level.
Solid plunging is not recommended with VAPOR inserts. Ramping (up to 2° max.) is recommended. Open step plunging (< .125” stepover) is acceptable.
Climb milling is generally recommended with high feed tooling. Cutter or part damage can occur with extended conventional milling. Exceptions exist: cutting scale, using long-reach tools.
Try to maintain at least 75% of the cutter diameter on the workpiece whenever possible. Hanging a cutter off to the side of your work is detrimental to tool life and performance.
Width of Cut (WOC) should be 60-75% of cutter diameter whenever possible. A slight scalloping effect between passes is acceptable. For longer-reach tools, this is especially important – cutting pressure should be on both sides of the center line.
High-feed milling produces a thick chip that is efficient at carrying away heat. Combine this with running a slightly lower SFM than normal to get optimum tool life.
Technical Considerations
Always use anti-seize compound on screws
Change insert screw every 10 inserts.
Use the shortest-length tool holder (end mill holder) for maximum rigidity; the shank of the cutting tool should be up inside the machine spindle taper whenever possible.
Thoroughly clean pocket and screw at each insert change.
Use tool holders appropriate for roughing operations: end mill holders and power chucks recommended; collets are not recommended.
