  • Modular method and system for setting fixed-angles of modular tools
    Patent number: 4961268
    Abstract: A modular method and system for setting fixed angles or revolving triads of interlocking holes of a hole type modular tooling system which are critically embodied in seven fixed-angle setting disks in each of which there are a few triads of holes that form certain angles. Selective use of not more than two of four disks can set up any fixed angles in 0.5.degree. increments, or selective use of not more than four of the seven disks can set up all the fixed angles in 30" increments. This modular system offers full angular adjustability, and permits precise and fast setups of small and compact constructions with good rigidity and stability.
