3.25.1.50 CYCLE4077 - surface grinding with infeed at the reversal point and cancel signal
Syntax
CYCLE4077(<S_GAUGE>, <S_I>, <S_J>, <S_K>, <S_A>, <S_R>, <S_F>,
<S_P>, <S_A1>, <S_A2>)
Parameters
No. Parameter Data type Meaning
1 <S_GAUGE> STRING Cancel condition for infeed:
● Number of a rapid input
● Logical expression
2 <S_I> REAL Infeed depth at the start
3 <S_J> REAL Infeed depth at the end
4 <S_K> REAL Total infeed depth
5 <S_A> REAL Grinding width
6 <S_R> REAL Feedrate for infeed
7 <S_F> REAL Feedrate for transverse infeed
8 <S_P> REAL Sparking-out time
9 <S_A1> AXIS Infeed axis (optional)
10 <S_A2> AXIS Oscillating axis (optional)
Function
The cycle is used for machining with a total infeed depth in infeed steps. The infeed depths at
the start and at the end can be different. There is a tangential motion between the infeeds. The
depth infeed is cancelled when the cancel signal of the rapid input is 1 or the cancel condition
is satisfied. A complete stroke is performed after the cancellation.
The positional data P2 to P5 can be negative or positive.
The specification of the infeed axis and/or oscillating axis is optional. If one or both parameters
are not specified, the cycle uses the first two geometry axes of the channel.
If the sum of the infeed depth at the start and end is 0 or the total infeed depth is 0, only one
sparking-out stroke is performed.
