Abstract
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.
Claims (11)
1. A method for calculating forming equipment component trajectories comprised of:
providing a forming die;
using a computer aided design (CAD) or a computer aided engineering (CAE) computer program to extend tangents from said forming die at various positions through the forming cycle, said tangents correspond to the location of one or more grippers during a forming process;
calculating the wrap angle, tension, elevation, tilt, and twist of each of said grippers at each of said tangents;
recording the wrap angle, tension, elevation, tilt and twist of each of said grippers at said tangent locations into a first computer file;
recording the initial 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 an appropriate location, speed, controller commands, and trajectory for said grippers during said forming 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 a product with the desired part geometry.
providing a forming die;
using a computer aided design (CAD) or a computer aided engineering (CAE) computer program to extend tangents from said forming die at various positions through the forming cycle, said tangents correspond to the location of one or more grippers during a forming process;

recording the wrap angle, tension, elevation, tilt and twist of each of said grippers at said tangent locations into a first computer file;
recording the initial 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 an appropriate location, speed, controller commands, and trajectory for said grippers during said forming 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 a product with the desired part geometry.
2. The method for calculating forming equipment component trajectories according to claim 1 wherein providing a stationary or non-stationary forming die.
3. The method for calculating forming equipment component trajectories according to claim 1 further comprising inputting said first computer file into a second computer program that can model said forming process using the data stored on said first computer file.
4. The method for calculating forming equipment component trajectories according to claim 1 further comprising transmitting said second computer file to said forming equipment via a computer network, telephone network, or a wireless network.
5. A formed component manufactured from the method comprising:
providing a forming die;
using a computer aided design (CAD) or a computer aided engineering (CAE) computer program to extend tangents from said forming die at various positions through the forming cycle, said tangents correspond to the location of one or more grippers during a forming process;

recording the initial 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 an appropriate location, speed, controller commands, and trajectory for said grippers during said forming 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 the desired part geometry.
providing a forming die;
using a computer aided design (CAD) or a computer aided engineering (CAE) computer program to extend tangents from said forming die at various positions through the forming cycle, said tangents correspond to the location of one or more grippers during a forming process;
calculating the wrap angle, tension, elevation, tilt, and twist of each of said grippers at each of said tangents;
recording the wrap angle, tension, elevation, tilt and twist of each of said grippers at said tangent locations into a first computer file;
recording the initial 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 an appropriate location, speed, controller commands, and trajectory for said grippers during said forming 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 the desired part geometry.
6. The formed component according to claim 5 wherein said blank is manufactured from a deformable material.
7. The formed component according to claim 6 wherein said blank is manufactured from a metal or a metal alloy.
8. The formed component according to claim 7 wherein said metal or metal alloy an aluminum or an aluminum alloy.
9. The formed component according to claim 8 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.
10. The formed component according to claim 6 wherein said blank is manufactured from a non-metallic material.
11. The formed component according to claim 10 wherein said non-metallic material is a plastic or a polymer.
