19534 Limit for changing cylindrical interpolation cutting point compensation in a
single block
[Data type] 2 Word
[Unit of data] mm, inch (input unit)
[Valid data range] 1 - 999999999
The following operation is performed, depending on the setting of parameter No.
19530:
1) When CYS = 0
If the amount of cylindrical interpolation cutting point compensation is
smaller than the value set in this parameter, cylindrical interpolation cutting
point compensation is not performed. Instead, this ignored amount of
cylindrical interpolation cutting point compensation is added to the next
amount of cylindrical interpolation cutting point compensation to determine
whether to perform cylindrical interpolation cutting point compensation.
2) When CYS = 1
If the amount of cylindrical interpolation cutting point compensation is
smaller than the value set in this parameter, cylindrical interpolation cutting
point compensation is performed together with the movement of the specified
block.
19535 Limit of travel distance moved with the cylindrical interpolation cutting point
compensation in the previous block unchanged.
[Data type] 2 Word
[Unit of data] mm, inch (input unit)
[Valid data range] 1 - 999999999
The following operation is performed, depending on the type of interpolation:
1) For linear interpolation
If the travel distance in a specified block is smaller than the value set in this
parameter, machining is performed without changing the cylindrical
interpolation cutting point compensation in the previous block.
2) For circular interpolation
If the diameter of a specified arc is smaller than the value set in this parameter,
machining is performed without changing the cylindrical interpolation cutting
point compensation in the previous block. Cylindrical interpolation cutting point
compensation is not performed according to a circular movement.
Note
Set this parameter as follows:
Setting > (setting for a rotation axis in parameter No. 1422)*4/3
where 4/3 is a constant for internal processing.
