Welcome to part 2 of our 3-part series about the basic CNC terminology that new users will encounter on a day-to-day basis. This article was designed to bring new machinists up to speed with words & phrases they are sure to hear and use regularly in their shop. Trailing off of yesterday’s article, here are 32 more terms to be familiar with.
What is a spindle on a Mill?
What is a spindle in regards to a Lathe?
The piece that rotates the material.
What is a machining center?
A Milling machine that’s enclosed and controlled by a computer program.
What is stock?
What is a machining strategy?
It is how a machinist decides the best way to machine a part.
What is a CNC Plasma machine?
These use mixtures of gases that produce a flame or torch hot enough to cut metals.
What is a Router and what is it primarily used for?
Routers and Mills have the same basic concept but are different. Mills are capable of more torque and used for metal cutting whereas a Router is used more for wood, plastic and lighter metals.
What is a job tree?
What is turning?
The action a Lathe performs.
What types are parts are cut on a Lathe?
What is a Laser?
What is Laser machining?
The technology of using very precise lasers to shape objects by cutting holes.
What is gas used for in machining?
To cool the workpiece while cutting and to produce a torch on a Plasma CNC.
What is Plasma?
What is Plasma cutting?
A torch cutting tool that is created by running a stream of gas through electricity.
What is a Mill?
A machine that has cutters to cut, shape, or finish material.
What is nesting?
What does simulate mean?
To create a simulation, likeness, or model of your part being cut in a virtual environment.
What is a simulator?
A program enabling a computer to provide a realistic imitation of the operation.
What does backplot mean?
What does extrude mean?
To force out or to force through a die.
What does parametric mean?
It means you can make something larger or different by a parameter.
What is parametric modeling?
CAD drawings that can be fully updated by changing numerical values without having to redraw a part.
What is 2-axis wire programming?
What is 4-axis wire programming?
When the upper and lower guides holding the wire move independently of each other in different directions.
What is a model?
The designed part when finished.
In machining, what is an axis?
What is a X-axis?
The width; left and right motion.
What is a Y-axis?
The length; front to back motion.
What is a Z-axis?
What is an A-axis?
It’s used along with the X, Y, and Z axes in 4 axis machining.
What is a B-axis?
Same as above. In 4 axis machining X rotates to A, Y rotates to B.
