Accessories and program-ming are important fundamentals of CNC machining.
A well-trained programmer is key to unlocking the capabilities of a computer numerical control (CNC) machine. In addition to the basic CNC components and direction of motion discussed in Part I last month, accessories and programming choices are important fundamentals. Mastery of these functions demonstrates the programmer's understanding of the CNC and provides the tools for optimum performance.
Accessorize with common sense
Knowing what a CNC machine can do also means knowing what it can't do. That's where accessories come into play. Many CNC machines are equipped with add-ons or enhancements such as probing systems, tool length measuring devices, post-process gaging systems and automatic pallet changers. The secret to accessorizing is knowing what a particular application demands. Some CNC machine accessories are made and supported by the machine tool builder and are documented in the machine tool builder's manual, while information about aftermarket accessories is in a separate manual.
