8025/8030 CNC PROGRAMMING MANUAL 161
The following points should be borne in mind when programming this canned cycle:
1. The definition of the pattern must not include point A because it is identified by P0
and P1.
2. The machining conditions (feedrate, spindle rotation, etc.) must be programmed
before calling the cycle.
3. The parameters must be entered either in the cycle calling block or in previous
blocks.
4. The exit conditions of the cycle are G00 and G90.
5. The pattern can be made up by straight lines, circles, roundings, tangential approaches,
tangential exits and chamfers.
6. Absolute or incremental programming can be used.
7. In the definition of the pattern no T function can exist.
8. The approaching and withdrawing movements are carried out in rapid and the rest
at the programmed feedrate.
9. The cycle is completed on the starting position of the tool.
10. Tool radius compensation (G41,G42) can be used.
11. The coordinates values (X,Z) of the point from where the cycle is called must be
different from P0 and P1 respectively. Otherwise error code 4 will be generated.
12. The machining movements will be made at the programmed feedrate.
Note: No polar programming allowed. G02/G03 must be programmed with X Z I K.
