Title: Cutting tool fracture recognizing function
Inventor: MORIMOTO MANABU
IPC: B23Q17/09
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To prevent secondary damage to a tool holder, a work and so on by providing a function of instantaneously recognizing a fracture of a cutting tool to give a warning. SOLUTION: During non-cutting of a machine, the positional relationship between a cutting tool and a work 3 is such that as an electric circuit is open, an electric current will not flow to the chuck 4 side. If the cutting tool is normal during cutting operation, a ceramic part A and the work 3 come into contact with each other, so that a feeble current flows to the chuck 4 side. After that, when the cutting tool is broken, a metal part B and the work 3 come into contact with each other, so that much more current flows. The respective conditions can be discriminated according to the magnitude of an electric current. This signal is guided to a control device. If chips are caught in the cutting tool so that the metallic part B and a holder 1 are electrically put in the connecting state, it becomes a signal of a cutting tool fracture.
