A very simple cnc milling program example which shows how a simple slot can be machined.Another such program example which mills a pocket the same way but in a taper is here CNC Milling Machine Programming Example for Beginners.Slot Milling Program ExampleSlot Milling Sample CNC ProgramN10 G00 G90 X

G84 tap cycle is one of the mostly used function of CNC machining centers.This G84 tapping cycle example program illustrates the use of tapping in an easy to understand way.G84 tapping cycle is a modal G-code, so is cancelled with G80 otherwise it will execute tap operation on every X and/or Y move.

Fanuc G68 Coordinate Rotation G-Code makes it easy for cnc machinist to run a pattern of operations in a rotated angle.Here is a basic cnc programming Example which helps to understand the actual working of G68 coordinate rotation.Fanuc G68 Program ExampleT1 M6G0 G90 G40 G21 G17 G94 G80G54 X20 Y0 S1
