10. 3. Pneumatic drive technology: It is used as at the gripper for manipulating delicate objects, e.g. used in glass industry. The robot operates from compressed air and they are activated tools. Limitation: Built in compliance of air, i.e. air can be compressed, creates noise while operation. Application: Used in pick and place operations in glass industry
11. II. Work Envelope/Coordinate Geometry : Work Envelope is defined as locus of points in 3 Dimensional space that can be reached by the wrist of robot. It consists of Rotary/Revolute motion about an axis and Translation motion along an axis (i.e. linear/sliding/prismatic/translate)

Editor's Notes
RP is an automatic process for manufacturing parts, tools and even assemblies directly from their CAD models without the use of any cutters, tools or fixtures specific to the geometry of the object and without any human intervention anywhere in the process. The idle time of a CNC machine is mainly due to the waiting for the NC programs which are prepared by humans. Therefore, the process of art-to-part is really not fully automatic in CNC. Therefore, RP is increasingly becoming an attractive alternative to CNC since it is more automatic than the CNC machines. It is one of the time compression techniques as it cuts down product development and productionizing cycle times. Therefore, it is an effective tool where time to market matters. As far as its construction is concerned, it is also a CNC machine. The only difference is that it is an additive process presently. Today’s RP machines are 2.5 axis machines. To meet the requirements of advanced slicing strategies, 5 axis RP machines are under various stages of developments at various parts of the world. Therefore, it is an appropriate topic for discussion in this forum.
