Investigation of the cutting tool groove 3-D scanning measurement system and its instrument

In this paper intelligent technology of 3D complicated surface scanning measurement which is associated with typical problems for the cutting tool groove measurement is discussed and some special algorithm are introduced. The 3-D scanning system can be used not only to input the parameters of solid model for tool CAD/CAM system and as a constitutions of the measurement geometry modelling system which is useful to the design and copy of tool groove but also to measure machining error of mould of the cutting tool. The experimental results show that the measuring precision of the system is up to the design requirements.
