Control method of numerical-control drilling and tapping machine tool magazine

The invention relates to a control method of a numerical-control drilling and tapping machine tool magazine, which is realized by the following steps: a programmable controller transmits a command for controlling forward or reverse rotation of the tool magazine to an electronic brake; the electronic brake starts a tool magazine device to operate according to the command of the programmable controller; a position detection transducer transmits a detection signal back to the programmable controller; by the calculation and processing of the programmable controller, when the detection signal transmitted back satisfies the command requirement, the programmable controller instantly transmits a command to the electronic brake; and while receiving the command, the electronic brake instantly stops the operation of the tool magazine device and simultaneously generates a direction electromotive force to complete the braking movement, so that the tool magazine device can precisely and reliably operate and stop according to the command of the programmable controller. The invention enhances the precision and stability of control on the tool magazine of the numerical-control drilling and tapping machine, controls the production cost, reduces the failure rate and facilitates maintenance and service.
