PURPOSE:To shorten the cutting time by making such that one turret will arrive to the starting position of cutting when another turret is performing cutting. CONSTITUTION:Informations such as the cutting finish point of first turret, the feeding speed, current position of second turret, the starting point of cutting and the moving speed are stored in memories 21-25 to produce signals which are fed to an operating means 26 to operate the cutting position of first turret at the time point when second turret may be moved. The operation results are fed together with the signal from current cutting positon detecting means 27 of first turret to decision means 28 to decide whether the operational results will match with the detection signal. Control means 29 is functioned on the basis of the output from decision means 28 to move the second turret. With such arrangement, the cutting time can be shortened. |
