6. Conclusion
This software uses Foxbase+ to generate on-screen menus that are intuitive and concise. Foxbase+'s database management features make it easy to store the items needed for tool design and locate them. In order to overcome the weakness of Foxbase+'s poor computing power, VC++ is used to calculate the tool structure parameters, and the interface program is used to realize data communication between the two languages.
After the tool structure parameters are determined, the worm wheel hob work diagram can be conveniently and quickly drawn by calling the pre-programmed Autolisp parameter drawing program, eliminating the cumbersome procedure of interactive drawing.
The programming method of this software is also suitable for CAD of other types of tools.
