Custom Combination Tooling allows two or more tools to follow a single hit applied by Auto Tool. You can do this manually through features like Single Punch, or you can follow the steps in this article to achieve the same result through Auto Tooling.
Note: To see this process in action, check out the Custom Combination Tooling webinar.
How to set up custom combination tooling
You can set up each punch machine to have its own tooling combinations based on the needs of your parts and the tooling available to each machine. To get started, you need to choose the conditions in which the tooling will be applied. To do this:
- On the Tools Help tab, click Technology Setup.
- Choose the Machine Parameters tab, then expand your machine’s name in the side menu.
- Select Punch Parameters, then choose the Custom Combination Tooling
Expand the Material that the tooling will be used for.
Note: If there are no materials or you want to add a new one, click Add (on the right side of the window). Then select the new material, enter a Material name (also on the right side of the window), and press Enter.
- Expand the Trigger Type. This is the tool type (round, special tap, drill, etc.) that is used to trigger the auxiliary tools.
Set the quality by selecting it, then entering the Quality value on the right side of the screen and pressing Enter to confirm.
Note: The quality value here must match the quality value of the contours you want to automatically apply the tooling combination to.
- Expand the Quality to display Thickness.
- Set the thickness by selecting it, then entering the Thickness value on the right side of the screen and pressing Enter to confirm.
- Expand the Thickness to display the Trigger Tool.
Set the dimensions for the trigger tool by selecting it, then entering the dimensions on the right side of the screen and pressing Enter to confirm.
Note: If you chose a special trigger tool, be sure to enter the exact name of the tool shape file assigned to it (without the .STF extension). This selects the exact tool to use as the trigger tool.
- Expand the Trigger Tool to display the Auxiliary Tool.
Add and set as many Auxiliary Tools as needed. Be sure to select the correct Tool Type on the right side of the screen and enter any corresponding dimensions. The end result should look something like this:
- When you have finished setting up your conditions and tools, remember to click OK to save your changes.
When all matching conditions are found on a contour (Material > Trigger Type > Quality > Thickness > Trigger Tool), all auxiliary tools included for that condition will be applied to the hit. This makes it easy for you to automatically apply multiple hits to a single contour, whenever these conditions are met.
Combination tooling can be useful in a number of cases. For example, if a large hole punch can’t be used on thick material because it exceeds the tonnage limit of the machine, you might be able to resolve this issue by punching a relief with a smaller tool first.
To do something like this, set the trigger tool to the full diameter of the hole, using the relief tool as the trigger tool. Be sure to set all other conditions (material, quality, thickness, etc.) to the correct values as well. Once the tooling is applied to the nested part, use Tool Sort to ensure the relief hit occurs first and then the full diameter hit.
Another example is a case where you want to create a hole for a carriage bolt. Something like this might require you to hit the contour with a round large enough to accept the bolt shaft. Then, you might need a countersink tool to accept the head of the bolt. Finally, you’d use a square tool to accept the square shank of the bolt.
To do something like this, set the trigger tool to match the geometry on the part that will trigger the auxiliary hits (most likely the square or round tool for the bolt). Ensure all the other conditions (material, quality, thickness, etc.) are the values you need. Then apply tooling and use Tool Sort on the nested parts to ensure the correct hit sequence.
