System and method for distributed machining simulation

A system in a communication with a set of remote hosts for simulating machining of a workpiece according to machining instructions for moving a machining tool with respect to the workpiece, the system comprising:

• a memory to store the machining instructions and a model of the workpiece;
• a processor to
• partition a model of the workpiece into nonintersecting volumes to produce a set of sub-workpieces;
• and
• modify the machining instructions for each sub-workpiece to produce a set of groups of modified machining instructions different from the machining instructions, each group of the modified machining instructions is associated with a sub-workpiece and includes effective machining instructions that move the machining tool through the sub-workpiece and at least one fake machining instruction that moves the machining tool through the model of the workpiece outside of the sub-workpiece;
• and
• a transceiver to
• transmit to each remote host over a communication link the group of modified machining instructions associated with the corresponding sub-workpiece and
• receive from each remote host, in response to the transmitting, the geometry associated with the corresponding sub-workpiece,
• wherein the processor reconstructs a representation of the machined workpiece using a portion of each geometry within the volume of the corresponding sub-workpiece.

A non-transitory computer readable storage medium embodied thereon a program executable by a processor for performing a method, the method comprising:

• partitioning a model of the workpiece into nonintersecting volumes to produce a set of sub-workpieces;
• modifying the machining instructions for each sub-workpiece to produce a set of groups of modified machining instructions different from the machining instructions, each group of the modified machining instructions is associated with a sub-workpiece and includes effective machining instructions that move the machining tool through the sub-workpiece and at least one fake machining instruction that moves the machining tool through the model of the workpiece outside of the sub-workpiece;
• causing the remote hosts to simulate the machining of the workpiece using at least one group of the modified machining instructions to produce geometries of a machining simulation of the workpiece, each geometry is associated with a corresponding sub-workpiece;
• and
• determining a representation of the machined workpiece using a portion of each geometry within the volume of the corresponding sub-workpiece.
