摘要:
A processing simulation method and apparatus is provided, which can appropriately detect interference between a tool processing area and a shape model of a material without being affected by the accuracy of expression of a tool movement path and the shape model. A tool shape model for processing a material, that includes a strict tool shape, and a tool shape model for checking interference, that is included in the strict tool shape, are generated by tool model setting unit according to an error range set in consideration of the tool movement path and the expression accuracy of the shape model, and the processed material shape model is generated by generating a tool processing area shape model from the tool movement path during processing feed and the tool shape model for processing the material and removing the tool processing area shape model from the material shape model. The tool processing area shape model is generated from a tool movement path during fast feed and the tool shape model for detecting the interference, and the interference between the tool processing area shape model and the material shape model is detected.

When a material shape model is separated in shear through processing, a shape model of a material in a state of being suspended remains in mid-air, and thus, interference is detected excessively. In order to prevent the excessive detection of interference, in a processing simulation method for generating a shape model of a processed material from a shape model of a material and a shape model of a tool processing area which is defined from a shape model of the tool and a movement path of the tool, the shape model of the material being separated into a plurality of shapes by processing is detected; a material shape to be cut-off is extracted from the separated material shapes; and the extracted material shape to be cut-off is excluded from subject of simulation.

Even in an uncuttable state in which an actual rotational direction of a main spindle is not matched with an actually cuttable main spindle rotational direction of a tool, an interference check between a workpiece and the tool is performed. Accordingly, the cuttable main spindle rotational direction of the selected tool or the uncuttable main spindle rotational direction is compared with each main spindle rotational direction of a working machine during execution of a simulation, and it is determined whether an interference check between the tool blade edge and the workpiece is necessary on the basis of the comparison result. When it is determined that the interference check is not necessary in the step above, the interference check between the tool blade edge and the workpiece is not performed. When it is determined that the interference check is necessary, the interference check between the tool blade edge and the workpiece is performed. When the interference therebetween is present, abnormality is detected.

A level difference or a uncut portion is prevented from being left between adjoining worked regions without forming any useless worked region. A lathe sectional shape forming unit (222) produces a sheet model of a lathe sectional shape in an X-Z plane on the basis of the solid model of a lathe shape formed by a lathe shape forming unit (220). A first/second step working sectional shape forming unit (227) produces sheet models of the worked sectional shapes of the first step and the second step on the basis of the sheet model of the lathe sectional shape, a step dividing position and an overlap amount. A first step disused shape deleting unit (229) and a second step disused shape deleting unit (230) delete the shape needing no work, from the sheet models of the worked sectional shapes of the first step and the second step.
