Virtual programming of formed component trajectories
View Patent ↗This invention discloses a method for calculating gripper trajectories in forming equipment. The method utilizes a computer aided design (CAD) or a computer aided engineering (CAE) computer program to calculate the appropriate location, speed, controller commands, and trajectory for each gripper used during a forming process.
1. A method for forming a component comprising:
providing a forming surface;
using a computer aided design (CAD) or a computer aided engineering (CAE) computcr program to extend tangents from said forming surface at various positions through a forming cycle, said tangents correspond to the location of one or more grippers during a forming process;
calculating wrap angle, tension, elevation, tilt, and twist of each of said one or more grippers at each of said tangents;
recording the wrap angle, tension, elevation, tilt and twist of each of said one or more grippers at said tangent locations into a first computer file;
recording initial one or more gripper positions, amount of pre- and post-stretch imparted on a blank, and initial blank size into said first computer file; and
inputting said first computer file into a first computer program to calculate appropriate location, speed, controller commands, and trajectory for said one or more grippers during said foming process, said first computer program produces an output that is then recorded in a second computer file that is read and executed by said forming equipment thereby producing said formed component with a desired part geometry.
2. The method according to claim 1 wherein providing a forming surface comprises providing a stationary or non-stationary forming surface.
3. The method according to claim 1 further comprising inputting said first computer file into a second computer program; said second computer program models said forming process using the data stored on said first computer file and displays said model.
4. The method according to claim 1 further comprising transmitting said second computer file to said forming equipment via a computer network, telephone network, or a wireless net work.
5. The method according to claim 1 wherein said blank is manufactured a deformable material.
6. The method according to claim 5 wherein said blank is manufactured from a metal or a metal alloy.
7. The method according to claim 6 wherein said metal or metal alloy is an aluminum or an aluminum alloy.
8. The method according to claim 7 where said blank is manufactured from an aluminum alloy selected from the Aluminum Association's 1XXX, 2XXX. 3XXX, 4XXX, 5XXX, 6XXX, 7XXX, or 8XXX series of aluminum alloys.
9. The method according to claim 5 wherein said blank is manufactured from a non-metallic material.
10. The method according to claim 9 wherein said non-metallic material is a plastic or a polymer.
