几何模型设计AbstractThis paper presents a new approach to design a
form milling cutter for precisely obtaining the complex free-
form surfaces. In this study， the intersection point of the rake
surface， helix flute and clearance flank is appropriately
defined due to its significant role in the design and grinding
performance. The angle-solid-block analysis is developed to
establish the new cutter geometrymodel. Hence， a new form-
milling cutter satisfying the requirements of machining
characteristics of workpiece can be designed. In addition，
the cutter geometric model can be adopted to map out the
measuring strategy with minimum measured points to attain
the exact geometric feature of cutter.
