B23P METAL-WORKING NOT OTHERWISE PROVIDED FOR; COMBINED OPERATIONS; UNIVERSAL MACHINE TOOLS (arrangements for copying or controlling B23Q)
Introduced: September 1968
Description
B23P encompasses metal-working operations and machine tools that do not fit within more specific IPC classifications (such as turning, drilling, or grinding). This subclass covers combined or multi-function metal-working processes performed on single machines, as well as universal machine tools capable of executing diverse operations on a workpiece. Typical technologies include turret lathes, transfer machines, and flexible manufacturing systems that integrate multiple metal-removal or metal-forming functions. The subclass excludes operations already classified under dedicated machine tool categories (B23B–B23H) but includes residual metal-working methods and apparatus requiring comprehensive or non-standard processing approaches.
