6. Interpolation Functions 

6.15  NURBS Interpolation 

 

 

104

 

 

Precautions 

 

(1)  Target axes for NURBS interpolation are 3 basic axes. 
 
(2)  Command the control point for all the axes for which NURBS interpolation is carried out in the 

1st block (G06.2 block). A program error (P32) will occur if an axis which was not commanded 
in the 1st block is commanded in the 2nd block or after. 

 
(3)  The first control point (G06.2 block coordinate value) should be commanded as the start point 

of the NURBS curve. Thus, command so that it matches the end point of the previous block. A 
program error will occur if the points do not match. 

 
(4)  The command range of the weight is 0.0001 to 99.9999. Even if the decimal point is omitted, 

the value will be handled as the one with a decimal point. 

 

If "1" is commanded, the result will be the same as "1.0". If more than 5 digits are commanded 
after the decimal point, a program error (P33) will occur.

  

 
(5)  The knot command cannot be omitted, and must be commanded in each block. A program 

error (P33) will occur if omitted. 

 
(6)  As with knot, in the same manner as weight, up to 4 digits can be commanded after the 

decimal point. Even if the decimal point is omitted, the value will be handled as the one with a 
decimal point. 

 

If "1" is commanded, the result will be the same as "1.0". If more than 5 digits are commanded 
after the decimal point, a program error (P33) will occur.  

 
(7)  As with knot, command the same or greater value than the previous block. If a smaller value 

than previous block is set, a program error (P551) will occur.  

 
(8)  NURBS interpolation cannot be applied during graphic check (continuous/step check). 
 

Linear interpolation that connects the control points is applied during graphic check.  

 

(9)  NURBS interpolation mode is canceled with Reset(Reset1/Reset2/Reset&Rewind). 

 

(10) NURBS interpolation can be commanded in only the following modes. If NURBS interpolation 

is commanded in other than the following modes, the program error (P29) will occur.
