System and method for automatic support device generation

1. A method for automated fixture manufacture, comprising:

receiving a virtual part from a user account;

identifying a plurality of potential retention sides on the virtual part, each potential retention side comprising a set of features extending from the potential retention side;

for each potential retention side of the plurality of potential retention sides, generating a plurality of potential retention rotations in a plane parallel the potential retention side;

generating a plurality of potential virtual fixtures, comprising: for each potential retention rotation of the plurality generating a potential virtual fixture based on: the set of features extending from the respective potential retention side and the respective potential retention rotation;

for each potential virtual fixture of the plurality of potential virtual fixtures,

determining a workholding confidence score;

selecting a virtual fixture from the plurality of potential virtual fixtures based on the respective workholding confidence score;

controlling manufacture of a physical fixture corresponding to the virtual fixture; and

controlling manufacture of a physical part using the physical fixture, the physical part corresponding to the virtual part.

2. The method of claim 1 , further comprising: retrieving a plurality of virtual stock fixture pairs, each virtual stock fixture pair comprising a first virtual stock fixture opposing a second virtual stock fixture, wherein the plurality of virtual stock fixture pairs encompass every combination of standard stock fixture depth options for the first and second stock fixtures; wherein the potential virtual fixture is generated based on a combination of the potential retention rotation of the plurality and a virtual stock fixture pair of the plurality; wherein the potential virtual fixture is generated based on: the set of features extending from the respective potential retention side, the respective potential retention rotation, and the respective virtual stock fixture pair.

3. The method of claim 1 , wherein determining the workholding confidence score comprises:

determining a stiffness for a physical part corresponding to the virtual part;

determining a total contact surface area between the virtual part and the potential virtual fixture; and

determining moment of the virtual part fixed within the virtual fixture.

4. The method of claim 3 , wherein the workholding confidence score is calculated based on the stiffness, the total contact surface area, and the moment.

5. The method of claim 1 , further comprising, for each potential virtual fixture of the plurality of potential virtual fixtures, determining a manufacturability score for the potential virtual fixture, wherein the virtual fixture is selected based on the respective manufacturability score.

6. The method of claim 1 , wherein selecting the virtual fixture comprises selecting the potential virtual fixture associated with an optimal workholding confidence score.

7. The method of claim 1 , wherein generating a potential virtual fixture further comprises:

identifying voids in the virtual features extending from the potential retention side; and

generating plugs for the identified voids.

8. The method of claim 1 , wherein generating a potential virtual fixture further comprises: adding clearance to internal corners in the virtual fixture.
