4962

M code for specifying a spindle positioning angle

[Input type] Parameter input

[Data type] 2-word spindle

[Valid data range] 6 to 9999999

Two methods are available for specifying spindle positioning. One
method uses axis address for arbitrary-angle positioning. The other
use an M code for half-fixed angle positioning. This parameter sets an
M code for the latter method.
In this parameter, set an M code to be used for half-fixed angle
positioning based on M codes.
Six M code from M

to M(

+5) are used for half-fixed angle

positioning, when

is the value of this parameter.

•

When the number of M codes is set in parameter No. 4964, let

be the value set in parameter No. 4962, and let

be the value set

in parameter No. 4964. Then,

M codes from M

to M(

-1)

are used as M codes for half-fixed angle positioning based on M
codes.

The table below indicates the relationship between the M codes and
positioning angles.

This parameter sets the number of M codes used for Half-fixed angle
positioning using M codes.
As many M codes as the number specified in this parameter, starting
with the M code specified in parameter No.4962, are used to specify
half-fixed angle positioning.
Let

not duplicate other M codes.

Type A A compensation vector perpendicular to the block next to the startup block or the block preceding

the cancellation block is output.

Type B A compensation vector perpendicular to the startup block or cancellation block and an

intersection vector are output.

Type C When the startup block or cancellation block specifies no movement operation, the tool is shifted

by the cutter compensation amount in a direction perpendicular to the block next to the startup or
the block before cancellation block.

When the block specifies movement operation, the type is set according to the SUP setting; if
SUP is 0, type A is set, and if SUP is 1, type B is set.

offset number (wear offset number when the tool geometry/wear
compensation function is used).

[Input type] Parameter input

[Data

type]

Word

[Valid data range] 0 to 999

When using memories common to paths, set the number of common
tool compensation values in this parameter.
Ensure that the setting of this parameter does not exceed the number
of tool compensation values set for each path (parameter No. 5024).
[Example 1]

When parameter No. 5029 = 10, parameter No. 5024 (path 1) =
15, and parameter No. 5024 (path 2) = 30 in a 2-path system, tool
compensation numbers 1 to 10 of all paths are made common.

[Example 2]

When parameter No. 5029 = 20 and the other conditions are the
same as for Example 1, tool compensation numbers 1 to 15 are
made common.

NOTE

1 When a multi-path system involving the machining

center system and lathe system is used, memories
are made common in each system.

2 In each of the machining center system and lathe

system, the same unit of tool compensation values
needs to be used.

3 Ensure that the setting of parameter No. 5029 does

not exceed the number of tool compensation
values for each path (parameter No. 5024). If the
setting of parameter No. 5029 exceeds the number
of compensation values of a path, the least of the
numbers of compensation values in all paths is
made common.

4 When 0 or a negative value is set, memories

common to paths are not used.
