G43.4 Tool center point control, type 1

Mazak (EIA) G-code · Mill

Five axis TCP. The control keeps the tool tip on the programmed X Y Z point while the rotary axes move, so the program is written for the tool tip. Used on Variaxis and Integrex in milling.

Format

G43.4 H [X Y Z A B C]

Addresses

Address	What it does
`H`	Tool length offset number
`X Y Z`	Tool tip position in the work coordinate system
`A B C`	Rotary axis angles

How it works

Modal. Cancel with G49.

Example program

T08 M06 (.500 BALL MILL)
G90 G54 G00 B0. C0. (ROTARIES TO ZERO)
G43.4 H08 X2. Y0. Z2. (TCP ON)
G01 Z.5 F50. (APPROACH)
…

The full 7-line example is in the app. Example is in inch. Check offsets and clearances first.

Watch out for

The tool length must be correct or the tip path is wrong in every tilted position.
Cancel with G49 before a tool change and before G28.
The CAM post must be set for TCP output, not for pivot point output.
