Automatic programming and simulation apparatus

An automatic programming and simulation apparatus comprising:

• a display device having an image displaying function;
• an inputting device having a data inputting function;
• an automatic programming section comprising a product configuration data storage section for storing therein product configuration data, a workpiece configuration data storage section for storing therein workpiece configuration data, a tool file for storing therein tool configuration data, a cutting condition file for storing therein cutting condition data for each blank material and for each tool, an interactive inputting/editing section which stores product configuration data, workpiece configuration data, tool data and cutting condition data interactively inputted from the display device and the inputting device in the product configuration data storage section, the workpiece configuration data storage section, the tool file and the cutting condition file, respectively, upon reception of the inputted data to allow for edit of the data stored in the product configuration data storage section, the workpiece configuration data storage section, the tool file and the cutting condition file and generates programming base data on the basis of the data stored in the product configuration data storage section, the workpiece configuration data storage section, the tool file and the cutting condition file, an NC program converting section which creates an NC program on the basis of the programming base data generated by the interactive inputting/editing section, and an NC program storage section for storing therein the NC program;
• and
• a simulation section comprising an image data generating section which reads the NC program from the NC program storage section for successively analyzing execution blocks of the NC program and successively generates pixel data indicative of a tool configuration and a workpiece configuration for the respective execution blocks, and a graphic section which displays the tool configuration and the workpiece configuration on the display device on the basis of the pixel data generated by the image data generating section;
• wherein the display device and the inputting device constitutes a functional section having a coordinate inputting function to input a coordinate position on a screen image displayed on the display device;
• wherein the image data generating section generates image data including pixel data updated from pixel data generated at the end of each machining process and process specification information specifying the corresponding machining process;
• wherein the simulation section comprises a data edit transition section which receives the coordinate position inputted on the screen image displayed on the display device by means of the inputting device and the display device to detect process specification information related to a pixel corresponding to the inputted coordinate position on the basis of the inputted coordinate position and image data generated by the image data generating section and serving as the base of the currently displayed image and transmits the detected process specification information to the interactive inputting/editing section to cause the interactive inputting/editing section to perform a data editing operation for a machining process specified by the process specification information received by the interactive inputting/editing section.
