For this demonstration tool to grind the root of a blade, the system is comprised of two tools: the bond station and the transfer tool. There are multiple transfer tools, one for each operation. This is only one example of the many possibilities that are available to the user of the Blue Photon System. The application of adhesive workholding can run from simple, single manual tools, to completely automated manufacturing systems running multiple part numbers.
Why is it called a transfer tool?
The hard to load part datums are transferred to the zero point locating datums. Each part goes through the same bond station. Another plus is that the transfer tools do not need to be the same because the datums are in the bond station, not the shuttle (transfer tool). The adhesive makes up the difference in the transfer tool build and also in casting variation.
Your machine fixture becomes an off the shelf item, i.e. an Erowa Chuck, and all your parts can use the same system. The only difference between the parts is the bond station and how the transfer tool is designed for the part. The part that goes into the machine is the same, simplifying your fixturing.
Refer to the numbers above to locate key areas of the datum transfer process.
The transfer tool is next loaded into the bond station.
Next, the part is loaded into the nest. In this case a turbine blade.
Next, the transfer tool is brought up to the part. This can be done either manually or automatically.
Next the UV light source is activated, curing the adhesive.
The part is now attached to the transfer tool. The part is unclamped and the transfer tool is retract.
The transfer tool is unclamped and removed from the bond station along with the part.
The part is ready to be processed as soon as it’s removed from the bond station.
