Insert Drill Demo Summary

Insert Drill ModeThe objective of the MCD1816 demonstration is to show how innovative tooling applications can reduce the total number of tools required to produce molds.

Process Benefits

Guide pin holes can first be insert drilled then finish bored with a ball end mill or up to a face mill, depending on the diameter of the pin hole. This machining is accomplished with Helical interpolation using Flush Fine machining parameters.
