CNC Vocabulary

2. a sequence of steps in a g-code program
6. the amount by which a dimension may vary
7. using a special tool to create grooves on a diameter of the part using a cutting motion perpendicular to the spindles rotational axis
8. a command to pause the program for a specified length of time
10. a linear axis of motion (horizontally) along the long side of the machine table
11. an interface for machining that is done at the controller
13. a single step in a g-code program
14. programs that allow you to digitally create a part that can be milled, 3D printed, or rendered
16. a linear axis of motion (horizontally) along the short side of the machine table
17. plunging a bit into a part to create a hole that's the diameter of the bit
18. a cutting pass using a tool that moves parallel to the spindles rotational axis to create an outer diameter on a part

1. how fast the tool moves through the material, commonly measured in inches per minute (IPM)
3. the rate of rotation the tool moves in the spindle, measured in revolution per minute (RPM)
4. calculations to determine the best way to cut through material.
5. clamp an apparatus or structure designed to hold your work or the material you are cutting with your CNC machine
9. a linear axis of motion (vertically) along the machine column
12. raw material that a part is machined from
15. a cutting pass using a tool that moves perpendicular to the spindle's rotational axis to create a face or shoulder on a part
