6. INTERPOLATION FUNCTION
B--63003EN--1/02

Exponential interpolation exponentially changes the rotation of a
workpiece with respect to movement on the rotary axis. Furthermore,
exponential interpolation performs linear interpolation with respect to
another axis. This enables tapered groove machining with a constant
helix angle (constant helix taper machining). This function is best suited
for grooving and grinding tools such as end mills.

SPN
[Data type] Bit type
SPN The amount of linear axis division (span value) in exponential
interpolation is:
0 : Specified with parameter No. 5643.
1 : Specified using address K in a block containing G02.3/G03.3. When
address K is not specified, the value set with parameter No. 5643 is
used.
5641
Linear axis number subject to exponential interpolation
[Data type] Byte type
[Valid data range] 1 to number of controlled axes
This parameter sets the ordinal number, among the controlled axes, for the
linear axis to which exponential interpolation is applied.
5642
Rotation axis number subject exponential interpolation
[Data type] Byte type
[Valid data range] 1 to number of controlled axes
This parameter sets the ordinal number, among the controlled axes, for the
rotation axis to which exponential interpolation is applied.
