Implemented methodology of process planning in software package<|>Includes all process planning activities to realize design of process plan<|>Solves planning activities like selection of machining operations, machine and cutting tools<|>Prepares route sheet for engineering drawing<|>Interprets part in terms of manufacturing processes to be used<|>Input from CAD system, output to CAM system
Parts grouped into families by manufacturing characteristics<|>Standard process plan established for each family<|>Retrieved for new parts in that family<|>Editing may be required for slight differences
Computer creates individual process plan from scratch automatically<|>Employs algorithms to make technical and logical decisions<|>Inputs comprehensive part description, not existing plans
A computer that is joined to the NC machine to make the machine versatile. Information can be stored in a memory bank. The program is read from a storage medium such as the punched tape and retrieved to the memory of the CNC computer.
One or more functions may be automatic: starting/stopping spindle, controlling spindle speed, positioning/guiding tool tip, controlling feed rate, changing tools
Cut away surplus material to leave a work piece of the required shape and size, produced to an acceptable degree of accuracy and surface finish
Able to hold work piece and cutting tool securely
Sufficient power to enable tool to cut work piece material at economical rates
Capable of displacing tool and work piece relative to one another to produce required work piece shape, with precision to ensure desired accuracy and surface finish
