11Scope of Practice Comparison
- In industry, the technician must learn
manufacturer specific processes, machine specific
limitations and capabilities, and high
performance characteristics - In these laboratories, you will learn general
processes and basic tooling considerations - The focus is on helping the designer and engineer
gain a basic understanding of the CNC
manufacturing processes, to springboard into
actual Manufacturing scenarios with high-level
knowledge of the involved processes
12Forethought Lowers Costs
With experience in manufacturing a part, the designer can avoid costly manufacturing procedures, and sell cost saving considerations to clients With experience in manufacturing a part, the designer can avoid costly manufacturing procedures, and sell cost saving considerations to clients
Unnecessary tool changes Material considerations related to cost of required tooling Design requiring special cutting tools Unnecessary surface finishes Assembly / disassembly complications Unnecessary part reorientation Using less expensive materials Using standard material sizes to reduce machining Are all machined surfaces necessary Are tolerances closer than they need to be
13Needs Statement
- The market to specialize as a Computer-Controlled
Machine Tool Operator is too specialized to
ensure an employment opportunity - HOWEVER
- The knowledge needed by engineers and designers
related to designing parts compatible with CNC
processes is essential in the control of
manufacturing costs
14Required Skills (laboratory specific)
- Identify CNC system components, and utilize media
input/output and storage of CNC programs - Develop an understanding of manual machine tool
practices - Develop an ability to manipulate the control
systems, and correctly control tool movement
without damaging equipment using downloaded media - Develop an ability to manipulate the components,
functions and operation of tools using the
Machine Control Unit (MCU). - Read and interpret CNC prints
- Perform Geometric Dimensioning and Tolerancing
(GDT) and inspection methods - Perform mathematical computations for CNC
Programming, use proper programming terminology,
and implement G machine code - Attempt to use typical machine shop practices, as
well as CNC programming and setup operations - Safe working practices at all times
- Clean working environment
- No Horseplay (issue warranting termination in
industry) - Tooling kept oiled and clean at all times
15Parting (pun intended) Thoughts
- If a machined part is to be square on one end and
round on the other, which end do you machine
first? Why? - If a hole must be drilled at a 45 degree angle to
a machined surface, how is the drill kept from
slipping? In CNC what does this mean? - Once you machine one side of a part, how do you
flip the part over to machine the other side, and
have everything line up?
