摘要： A spray coating simulation for a robotic spray gun assembly imports a discretized model of an object geometry. Next, the simulator imports a numerically characterized spray pattern file and a robot motion file having a plurality of motion positions, dwell times and orientations defining a motion path of the spray gun. The individual motion positions within the motion file are read and a determination is made as to which portions of the object geometry are visible at each motion position. Next, a coating thickness at each visible portion of the object geometry is computed, based on the specified spray pattern data, the dwell time and the orientation of the robot motion path, for each motion position. Finally, the total coating thickness over the object geometry is calculated.

摘要： A method of generating quality matrices indicating a relationship between critical to quality characteristics and key control parameters for levels of a process. A plurality of rows of a first matrix are designated as critical to quality characteristics and a plurality of columns of the first matrix are designated as key control parameters. Each critical to quality characteristic is assigned a critical to quality weight. An interaction weight is assigned between at least one critical to quality characteristic and at least one key control parameter. A score is then generated for at least one key control parameter in response to said critical to quality weight and said interaction weight.

摘要： A product design tradeoff method is provided. A transfer function, which generates an output in response to an input is obtained. A type of optimization to be performed is identified and the input to the transfer function is perturbed in order to achieve the type of optimization identified. Output information representing the output of the transfer function is then generated to provide the user with the result of the optimization. Generating the output information comprises generating a sensitivity matrix. The sensitivity matrix comprises a plurality of sensitivity values that indicates a relationship between a change in input versus a change in output, wherein each of the sensitivity values provides a corresponding numerical value for comparing an effect of the change in the input versus the change in the output.

摘要： An exemplary method of designing a manufacturing process comprises the steps of representing a workpiece as a plurality of triangular finite elements, representing the forming tools with mathematical equations which typically include cubic polynomials, simulating a deformation of the workpiece by the forming tools with a finite element model, wherein the finite element model is integrated with explicit integration. The method may be carried out with an apparatus which includes a memory device which stores a program including computer readable instructions, and a processor which executes the instructions. After the deformation of the workpiece has been simulated by the finite element model, the characteristics of the workpiece and forming tools can be modified to improve the final shape of the workpiece. After the finite element simulation produces an acceptable final workpiece shape, an actual workpiece can be formed with actual tools based on the simulation.
