6. INTERPOLATION FUNCTION
B--63003EN--1/02
478
With the involute interpolation function, an involute curve can be
machined. Cutter compensation C is also possible. The use of involute
interpolation eliminates the need to use short lines or arcs to approximate
an involute curve. Pulse distribution is no longer interrupted by the
high--speed operation of small blocks. As a result, smooth, high--speed
operation is possible. In addition, part programs can be created more
easily, and the required paper tape can be shortened.

This parameter sets the allowable limit of deviation between an involute
curve passing through a start point and an involute curve passing through
an end point for an involute interpolation command.
No. Message Description
241 ENDPOINT,I,J,K,AND
R ARE MISSING
The end point of an involute curve, I,
J, or K is not specified.
242 SPECIFICATION ERROR
(INVOLUTE)
An illegal value is specified for invo-
lute interpolation.
(1)The specified start point or end point
is located inside the base circle.
(2)Zero is specified for I, J, K, or R.
(3)The start point or end point is located
more than 100 turns from the beginning
of the involute curve.
243 END POINT NOT ON IN-
VOLUTE CURVE
The end point is not on the involute
curve that passes through the start
point, and is beyond the range speci-
fied with in parameter No. 5610.
