98-2 Objectives State the purposes of the Cyber Management System Define Multi-Tasking Machines List the advantages and describe the construction of Multi-Tasking Machines Identify the accessories and optional equipment available for Multi-Tasking Machines

98-3 Cyber Management System Comprehensive information-gathering system –Design of product –Every stage of manufacturing process –Includes everyone who plays part in manufacturing process Computer allows management to operate a factory in real time –Accessibility to all data

98-4 Multi-Tasking Machining Defined Ability to perform various manufacturing operations without manual intervention Can complete all operations required to manufacture part in single machine setup Allow industries to change manufacturing processes to improve productivity

98-5 Purpose of Multi-Tasking Machines Reduce number of machine tools required to manufacture a part to one Advantages –Fewer machines required –Parts not moved from machine to machine –Parts more accurate –Overall cycle time greatly reduced –Increased flexibility to handle parts –Improves cash flow

98-6 Types of Multi-Tasking Machines Wide variety –Basic model Single-spindle, single vertical turret machine –Most comprehensive model Twin turning spindles and twin machining turrets Sample: Mazak Integrex Model 200-III –Two spindles for front and back operations –Lower turret: 9 tools, Upper turret: tools

98-7 Machining a Complex Part First process –Grip part in pre-bored chuck jaws (left spindle) Turning, milling and drilling done on part extending –Automatically transfer part from first spindle to second spindle Finished right hand of part now in second spindle jaws Second process –All turning, milling and drilling on unfinished left-hand end of part

98-8 Accessories Cyber Production Module –Feature communication gears for machine operator Programming, ordering, fixturing, and tooling, notification of alarms, maintenance and scheduling and more Tool Data Management –Data tied to tool identification chip mounted in tool's retention stud Tool data automatically downloaded over network Flash Tool Holder –Cutting tool that can perform 12 machining operations without tool change
