VocabularyVocabulary

CNC - a computer that reads G-code instructions and drives a milling machine in order to milling a part

End mill - a cutting to similar to a drill bit in appearance with cutting edges on its circumference

PRZ - programmed reference zero

What’s g-code?What’s g-code?

A type of Industrial Standard Operation (ISO) codes.

We will use their conversational equivalents.

Coordinate SystemCoordinate System

Coordinate SystemCoordinate System (x,y,z) where

x axis parallels the front of the cnc mill Y axis parallels the side of the cnc mill Z axis parallels the height of the cnc mill

(x,y,z) = (0,0,0) or the Programmed Reference Zero is set before cutting to be a position at the top of the mill stock at its left front corner. This means that to cut the material, the end mill’s z coordinate will need to

be negative.

Using the graph paper provided draw a maze to be milled with an 1/8” end mill.

Write the g-code to mill it. Run the simulations in four views.
