Fixturing for mechanical prismatic parts with the input of 3D CAD data in the STEP standard

摘要

Fixturing plays an important role in process planning since it is the key factor to precision manufacturing. An expert process planning and fixturing system has been developed and implemented in Prolog. This paper presents the fixturing techniques applied to find supporting, locating and clamping faces for 3D prismatic parts. The fixturing systems are outlined and an example part is given.
