Once contact has been detected using an acoustic emission sensor, the tool will retract by
the acoustic emission sensor infeed amount minus the grinding infeed amount.
If no acoustic emission sensor input has been configured, the cycle will immediately switch
to the handwheel at the start of the operation.
Sequence
Approach allowance position, approach X starting position and Z starting position.
Start oscillating motion, infeed at reversal points.
The first infeed once oscillating motion has commenced is adjusted to ensure that all
additional infeed operations correspond to the infeed amount. This process is also performed
following interruptions, intermediate dressing and deselection of the handwheel override
function. The oscillating motion is not performed with the oscillation function, as this would
cause problems in terms of residual path deletion, and would overload the PLC.
Following interruption/dressing, an off-loading value is applied as the tool approaches the
machining start point.
At the end, the tool retracts by the retraction amount or machining continues at the end point
using a new technology. In other words, if the oscillating axis is at the X axis end or start
point and the allowance is correct, machining will continue from this point. As a result, it is
possible to combine any number of technology seats.
