Abstract
The automatic support device generation method includes: receiving a virtual part; determining a retention direction for the virtual part; determining a retention rotation for the virtual part; and constructing a support device based on the part, the retention rotation, and the retention direction.
Claims1
A method for automated fixture manufacture, comprising:
- a) 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;
- b) receiving a virtual part from a user account;
- c) 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;
- d) 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;
- e) generating a plurality of potential virtual fixtures, comprising:
- for each combination of a potential retention rotation of the plurality and a virtual stock fixture pair of the plurality, generating a potential virtual fixture 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;
- f) for each potential virtual fixture of the plurality of potential virtual fixtures:
- 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;
- determining moment of the virtual part fixed within the virtual fixture;
- and
- calculating a workholding confidence score based on the stiffness, the total contact surface area, and the moment;
- g) selecting a virtual fixture from the plurality of potential virtual fixtures, the virtual fixture comprising a potential virtual fixture having an optimal workholding confidence score;
- h) controlling manufacture of a physical fixture corresponding to the virtual fixture;
- and
- i) controlling manufacture of a physical part using the physical fixture, the physical part corresponding to the virtual part.
