This image explains the cusp height
of the tessellated STL surface compared to the original CAD model.
is one of the factors that affect the tool-chip contact area and tool-machined surface contact angle.
Sommerville then used the 3D offset finishing strategy, which he says delivers an excellent surface finish because the step-over is varied to give a constant cusp height
, both on steep surfaces and shallow contoured areas.
The morphological arrangement of the teeth in the sagittal plain has been related to the slope of the articular eminence, craniofacial morphology,3 lower incisor proclination, the incisor overbite,4 the molar cusp height
and lower arch circumference.5,6 However it is suggested that the curve of Spee has a biomechanical function during food processing by increasing the crush-shear ratio between the posterior teeth and the efficiency of Occlusal forces during mastication.7
There tends to be a harmony of steepness or flatness which in turn determines the cusp height
, fossa depth and occlusal tooth form of the posterior teeth.
(2004) have developed an algorithm for adaptive direct slicing and used the non-uniform cusp height
. The solid model is built in Unigraphics and imported to their stand alone C++ program in STEP format.
