In design and manufacturing area a CAD/CAM laboratory coupled with a computer-integrated manufacturing (CIM) laboratory provide hands-on experience and an understanding of the design to manufacturing concept.  Computer Integrated Manufacturing (CIM) embodies three components essential to the implementation of flexible design & manufacturing -- the means for information storage, retrieval, manipulation and presentation; the mechanisms by which to sense state, and modify substance; and the methodologies by which to unite them. The Computer Integrated Manufacturing Laboratory (CIMLab), founded in 1994, provides students and research associates with necessary facilities to contribute to the success of this goal. The CIM laboratory houses a fully computer-integrated manufacturing cell equipped with a robot, CNC milling machine and lathe, Allen-Bradley PLC and machine vision system.  Mazak CNC lathe, a Bridgeport CNC milling machine, and Brown & Sharp Gage 2000 R co-ordinate measuring machine (CMM) are also available in CIM laboratory.
