2.7 TOOL COMPENSATION

2.7.1 OUTLINE OF TOOL COMPENSATION

The tool compensation function is in the following
three modes.

. Tool length compensation

This function is for compensating the differences

in tool length, and is effective in the Z axis di-
rection,

Specified length compensation becomes

effective from the block in which G43 or G44 is
programmed together with an H code. It is

with HOO or G49.

. Tool position offset ( for simple compensation

for tool radius)

This function is for compensating for errors in

machined dimensions to be introduced by the radius
of tools. It is effective in the X, Y, and Z (4th t ) axis
directions.

It is effective only for the block in which

G45-G48 is programmed together.

. Tool radius compensation C

(for compensating

for tool radius effects with complicated machin-

ing contours)

This function is for compensating for the tool
radius effect with any given machining contours.
It is effective in X-Y , Y-Z, and Z-X planes.
It becomes effective from the moment

, or

G42 is commanded together with a D code, and
is

by G40.

2.7.2

TOOL OFFSET MEMORY

For the three groups of offsets, all the necessary
offset values must be stored in memory before-
hand.

The following number of offset values can be

stored in the tool offset memory.

Offset Value Storage

Basic

t Optional

1199

The setting range of offset values is as follows.

Linear axis

R o t a r y

Metric input

O - 999.999 mm

O- 999.999 deg

Inch input

O - 99. 9999 inch O- 999.999 deg

For the procedures of storing values into memory, refer
to 4.3.5.

SET AND WORK

2.7.3 H- AND D-FUNCTION (H, D CODES)

Two or

digits, following the address H or

D , specify tool offset numbers.

T o o l o f f s e t

number

The tool offset numbers 01 through 99 directly
correspond to the

offset-value memory num-

b e r s .

That is, when certain numbers are des-

ignated, the corresponding g offset values stored
in the offset memories will be used to offset the

tools .

Tool offset numbers 00 (HOO or DOO) have differ-
ent meanings depending on the respective offset
functions.

For details, refer to the descriptions

on the respective G functions.

H- and D-codes must be used properly according
to their functions.

The tool offset numbers 01 through

used freely in combination with the both H and
D codes.

Listed input values do not depend on metric/
input output system.
