Machinists that are new to manufacturing can find themselves in quite the hole when starting out. There is a lot to process at first, whether it’s learning how to use the new machine they just got or learning how to operate their software. Today’s article aims to alleviate some of the hardships of getting started by naming and defining some of the basic terminologies that are used in CNC manufacturing regularly.

What is a post processor?
A translator. Post Processors are used to generate NC programs that are specific to each individual CNC machine controller. The Post Processor drives the format of the G or M-code that will be produced and ultimately instruct your machine how to create your part.
What is G-Code?
A set of instructions understood by CNC equipment. G stands for Geometric and Code has to do with the systematic collection of numbers or symbols that are put together as a language to give instruction. It’s the language produced by a CAM system that is sent to the machine to make the machine cut the part.
In CAD, what is a solid?
A series of shapes used to design something. Sphere, Cube, Cone, Cylinder, and Torus are the 5 basic solids also called Primitives.
What is depth?
The distance a tool is cutting into a part, Z axis.
What is machining?
What is a dimension?
The measurement of something… height, width & depth.
In machining, what is a tool?
The cutter that removes material from your part.
What is a toolpath?
What is a 2D toolpath?
X-width (horizontal) and Y-length (vertical) movement a cutter takes 24.
What is a 3D toolpath?
X, Y, and Z-depth movement a cutter takes.
What is a tool database?
A customizable library for cutting tools.
What is a controller?
What is threading?
The process of machining a cut that spirals down the length of a cylinder
Alright, that concludes part 1 of our 3-part introduction to CAD-CAM terminolgy. Make sure to join us tomorrow as we continue to run through the list of CNC vocabulary that you are sure to hear on a daily basis in the shop! See you tomorrow.
