( IKA example 1 )
Machining of a contour with IKA
Y[mm]=100+160/3*COS[5/7*X[mm]])
from [X,Y]=[252,46.666] to [0,153.333]
Caution: This example does not take the tool offset
into account!
0. Preparation :
- Deactivate IKA 2
- Approach tool change point
- Error ID = 0
1. Structure of the table [ika3 data] :
- Input quantities 1..13 :
Angle 0, 30, ... , 360 degrees
in units of 10**[-3] degrees
- output quantities 1..13 :
Sine [0], ... , Sine [360 degrees]
in units of 10**[-4]
SIN=1 -> 10000=10 mm
2. Start and end pointer [ika2 data] :
- Curve 1 uses points 1...13
- Calculate curve 1
- [a] read error byte [> R30]
- [b] case statement for R30 :
Jump list for R30=1 .. 4 [error]
otherwise continue [R30=0] at N150;
scan [a] is repeated as long as
R30 =-1 or R30=-127
