- 175 -
Limitations
- Unusable functions
This function cannot be used with the following functions:
- G functions of group 01 listed below
Positioning
Circular interpolation, helical interpolation, spiral interpolation,
conical interpolation
Circular threading B
Involute interpolation
Exponential function
Three-dimensional circular interpolation
Spline interpolation
NURBS interpolation
- Cylindrical interpolation
- Polar coordinate interpolation
- Normal direction control
- Feed per revolution
Inverse time feed
- Parallel axis control, twin table control
When using this function for parallel axis control or twin table control,
set the same value in parameter No. 2524 for the master and slave axes.
Examples
- When a rotation axis is specified singly
Travel time when G91 G01 B10. F10. is specified
(1) When parameter No. 2524 = 10.0 (mm), the travel time is:
(seconds)47.1060*min)/(10/180/*(deg)0.10*)(0.10 =mmmm
π
(2) When parameter No. 2524 = 36.0 (mm), the travel time is:
(seconds)70.3760*min)/(10/180/*(deg)0.10*)(0.36 =mmmm
π
(3) When parameter No. 2524 = 0.0 (mm)
A movement is made at a maximum cutting feedrate.
- When a rotation axis and linear axis are specified at the same time
Travel time when G91 G01 X5. B10. F10. is specified
(1) When parameter No. 2524 = 10.0 (mm), the travel time is:
(seconds)78.3160*min)/(10/)180/*(deg)0.10*)(0.10()(0.5
