Numerical controlled device and numerically controlled machine tool

摘要

The program for a numerical control device for controlling a numerically controlled lathe includes translation commands for translating the tool and the machining mode switching commands for switching between the normal mode by which only the tool is translated and the Swiss mode by which both the tool and the work are translated. A machining program analyzer unit analyses the program commands into translation commands and the machining mode switching commands. In response to the machining mode switching commands, the interpolation data generator unit converts the commands for translating the tool two-dimensionally into translation data for the tool along a first axis and a translation data for the work along a second axis. Thus, the programming for the machine tool capable of operating both in the normal and the Swiss mode is made easier.
