The ballnose end mill is a special sort of tool. Its ability to mill up and down the contours of complex surfaces makes it invaluable to mold shops and other makers of 3D forms. And yet, the tool is lacking in a capability one might take for granted in other cutters: the ability to machine a flat surface.
A shop that wants to win cost savings from its cutting tool purchases is likely to take two factors into account: tool life and tool price. But that approach might be flawed.
This shop expedites 3D milling work by reducing its dependence on employees for all of the information-related tasks that occur before the machining center can start to cut.
How good is your shop at connecting its purchasing decisions to the operations that those decisions affect?
An article this month (Cutting Costs With Cutting Tools: Instead Of Life Or Price, Look To Capability) offers some representative cost figures to illustrate a straightforward point. Namely, tool life and tool price generally do not have a large impact on the cost of machining, but tool capability does.
A Silicon Valley manufacturer's survival strategy involves closer relationships with customers, and high speed machining is crucial to this. The shop pays particular attention to the process factors that affect high speed machining before the cut takes place.
