  1. Describing a Work System CNC MACHINING By Bill Carver

  2. The Purpose • The purpose of CNC Machining, is the cutting of materials into a specific form, designated from a particular data set. • This procedure allows the shaping of different materials without using a casting process. • The purpose of machining is to minimize human effort, and increase accuracy, by using computer and servo technology.

  3. The Inputs • The stock, which could be any malleable martial that can be cut by machining.

  4. The Outputs • The results from the process would be the actual piece of machined material produced from the CNC machine.

  5. Environment • The environment of this particular process, would be limited to temperature, and cleanliness. • Temperature plays a specific role due to the computer’s sensitivity to extreme hot and cold. • Cleanliness would be required due to the high precision nature of the machine, not to mention the computer control system.

  6. Qualifications • The CNC programmer/operatormust be able to take command of a CNC programming system that is capable of directing the machine to machine a particular piece of stock. • Humans are also required to prepare the machine for machining a particular job. • Humans do not play a role in the actual machining process.

  7. Physical Catalysts • A direct catalyst would be the data set used to direct the machine, these are the commands that are given to the machine in order to make it function; Another catalyst would be energy itself, without this the machine would not have power to function; Tools to perform stock mounting operations, that will be performed by the human operator. • The cutting tools or end mills that allow the machine to form the metal would also play a role as a catalyst.

  8. Sequence • A program for the machine is generated. • The machine is set with block and cutting tools. • Program is activated, and begins cutting. • Program finishes, material machining is complete.
