The present invention provides a method and an apparatus for generating post-machining three-dimensional shape data for a workpiece on the basis of an NC program. The three-dimensional shape data generating apparatus comprises: a stock blank lattice point generating section () which represents the shape of a stock blank for the workpiece by three-dimensional lattice point data (L) comprising a multiplicity of lattice points on the basis of stock blank shape data; a tool path processing section () which generates data indicative of a tool traveling region in which the tool is to move with respect to the workpiece on the basis of the NC program, tool shape data and the stock blank shape data, then removes lattice points located in the tool traveling region; and a shape data generating section () which generates the post-machining three-dimensional shape data for the workpiece on the basis of the remaining lattice points.

Method and apparatus for generating three-dimensional shape data

Tool path data generation apparatus () that can speedily and securely generate tool path data on the basis of CAD data. The tool path data generation apparatus () includes a feature data extractor () to extract features in relation to at least a three-dimensional shape of a workpiece, a tool/cutting data storage () to store a cutting mode etc. in accordance with a feature shape, a cutting method setting unit () to set an optimal cutting method for each feature shape on the basis of the extracted feature data and the stored tool/cutting data, and a tool path data generator () to generate tool path data on the basis of set cutting method. An operator doesn't have to input any data in generating tool path data, therefore tool path data can be speedily generated.

Tool path data generation apparatus for NC machine tool and numerical controller provided with it

The present invention provides a machining-related information generating apparatus, which speedily and correctly generates tool path data, and automatically generates operation information required for machining. The machining-related information generating apparatus comprises: a process/machining model data generating section ( ) which extracts product characteristic data from CAD data, then generates process data, stock blank data and machining model data; a machining-related information generating section ( ) which generates tool path data on the basis of the process data, the stock blank data, the machining model data and the like, then generates data of virtual workpiece configurations, and generates machining operation information data on the basis of the process data, the stock blank data, the tool path data and the virtual workpiece configuration data.
