ABSTRACT:
A system is provided for measuring tool wear of a rotating end mill. The system measures wear by monitoring the side-loading forces on the tool during cutting. The resultant side-loading forces FRES have tangential FT and radial FR components. The radial component FR increases correspondingly with tool wear. FRES and FT are measured directly and on the basis of these measurements FR is determined mathematically to provide an indication of tool wear.
