Cutting a punch

Cutting a Punch

Things that will be covered in this section.

• Editing geometry start/end points

• Applying additional tags

• Moving start points

From the menu select file > Open

Open the file - Punch.wkf

Select Machining > CAM Navigator,

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

Ensure the centre of a circle/arc selection icon is active and pick the second circle, the new approach/retract/start/stop will be created in this position.

Righthand click on the CAM-setup and select the properties option from the menu. *

Activate Use Pre-defined strategy and select Unattended bosses from the drop-down menu, click OK

Select the Wire tab in CAM Navigator, righthand click on the Project, select properties, choose a Piece material and Wire and click OK

*Tip - You can also lefthand double click on most options

Righthand click on wire and, select properties, click the Select technology from database button

and select a technology with a thickness of 50mm and 2 cuts, click OK

Note - This dialog will be different for each machine manufacturer

This will load-in the offsets and register settings for your machine, click the Set technology parameters for this cut button to see the register settings that have been loaded

Note - This dialog will look different for each machine manufacturer

Click OK

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.
