Machining will take place in the Z direction if no roughing allowance has been programmed
for Y.
A higher infeed amount can be used at the start of machining. 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 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.
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 using a new
technology, assuming that the end point of the first machining operation is the same as the
starting point for the new machining operation. 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.
