Abstract
A method for supplying cutting oil in a machine tool for cutting work pieces, including the steps of retaining cutting oil in a minimum reference quantity or an initial reference quantity in the cutting-oil tank, measuring a supply quantity per unit time q of the cutting oil flowing out from the cutting-oil tank and supplied to a cutting area of work pieces, either supplying the cutting oil to the cutting-oil tank by a quantity per unit time q′ larger than q and the supply is stopped in the case where the cutting-oil tank is filled, and the supplying and stopping are repeated as necessary, or supplying the cutting oil to the cutting-oil tank by a quantity per unit time equal to the supply quantity per unit time q.
Claims10
A method for supplying cutting oil in a machine tool for cutting work pieces, comprising the steps of:
- retaining cutting oil of a minimum reference quantity Qmin in a cutting-oil tank,
- measuring a supply quantity per unit time q of cutting oil which flows out from the cutting-oil tank and is also supplied to an area where work pieces are cut,
- setting a supply quantity per unit time q′ of cutting oil supplied so as to satisfy q′>q, and supplying the cutting oil to the cutting-oil tank according to the above supply quantity per unit time q′,
- stopping supply of cutting oil to the cutting-oil tank at a stage when the tank is filled with cutting oil according to the supply quantity per unit time q′,
- additionally supplying cutting oil to the cutting-oil tank according to the supply quantity per unit time q′ when a retained quantity of cutting oil in the cutting-oil tank reaches a minimum reference quantity Qmin due to said stopping, and
- repeating said steps of stopping and supplying according to the supply quantity per unit time q′ as necessary.
A method for supplying cutting oil in a machine tool for cutting work pieces, comprising the steps of:
- retaining cutting oil of an initial reference quantity Q0 in a cutting-oil tank,
- measuring a supply quantity per unit time q of cutting oil which flows out from the cutting-oil tank and is also supplied to an area where work pieces are cut,
- supplying cutting oil based on a cutting amount per unit time which is equal to the supply quantity per unit time q supplied to the cutting-oil tank.
