If the recognition on this part is done by
righthand clicking the model manager,
the result would be that a total of 6
features would be created on 3 different
setups, in this case it may be
acceptable but on models with a large
number of features this could make for
a very cluttered model manager window




To ensure that we only find features oriented in the Z direction we will
create a setup to use for the feature recognition,

Righthand click on the Model manager and select, Add
setup, the system will ask you to pick a face or element,
ensure the Face selection icon is active and pick the top
face of the punch as shown

The Cam navigator will now have a new Setup added to it, righthand click
the setup and run recognition to extract the punch feature

The result will be the addition of a single Boss feature to the previously
created setup, add a 2-axis wire EDM opperation to this feature.

The wire start/retract point for this operation has
been automatically generated from one of the
small circles.

You may have noticed that there are two circles drawn, this is because we
will be using 2 start points for this punch to reduce the chances of the
punch twisting during cutting.

Righthand click on the wire
operation and select Edit
geometry

Righthand click on Edit Tec points

You will now be pesented with a new
panel on the right of the screen, select
the Tags tab, then the Add button

Use the following parameters for this machining

Use distance for tag with tag distance of 1mm
Stop at end of tag cut = ticked with distance 0.4 *
Lead off distance 0.5mm
Upper nozzle 50mm
Lower nozzle 0mm

Select OK on the dialog


Righthand click Path-Lab from the CAM Navigator and run the wire path
simulation to check your part











* This will add an additional stop at the end of the job just prior to the
punch becoming detached, this will prevent the punch from accidentally
dropping, a light tap with a soft hammer will release the part.
