[0057] A control method of a CNC drilling and tapping integrated machine, the control steps are as follows:
[0058] step one:
[0059] Turn on the power of the mechanical and electrical control, start the controller and the machine, and observe whether the door-shaped mounting frame 15, the sliding frame 10, the left sliding piece 23 and the right sliding piece 28 are at the origin. If so, you can select the automatic return to the origin of the man-machine interface , Make the drill 5 and the tap 13 aligned, otherwise you need to manually move the door-shaped mounting frame 15, the sliding frame 10, the left sliding piece 23 and the right sliding piece 28 to the origin; then install the workpiece to be processed on the workpiece clamping table 4, tap Workpiece requirements in wire mode: aluminum profile and steel with a thickness of less than 10mm, and then install the tool according to the processing technology. If the tapping mode is selected, the drill 5 should be installed on the electric spindle when installing the tool, and the tap should be installed on the stepper motor. 13;
[0060] Step two:
[0061] Establish the required workpiece coordinate system, the coordinate value in the program is the coordinate value of this workpiece coordinate system, respectively in the man-machine interface "+X", "-X", "+Y", "-Y", "+ Z is for drill", "-Z is for drill", "+Z is for tap", "-Z is for tap", "Stop" button or external button controls XYZ, which is the drill axis forward, reverse, stop, forward point After the tool setting is completed, press the "Coordinate Confirmation" button on the man-machine interface, the program will establish the workpiece coordinate system, the user inputs the coordinate value is the absolute value of the workpiece coordinate system, and then the tap 13 axis Press "Double tool deviation calculation", then the tool setting action is completed;
[0062] Step three:
[0063] The selection mode is tapping mode, and there are three control modes; one: input the position to be tapped, multiple tapping positions can be input; two: when the turntable 3 is used for processing, the center of the workpiece and the center of the turntable 3 are concentric Circle, how many degrees to turn the turntable to process. Three: After selecting a point and inputting the radius and angle, it will be processed. At this time, the point is the absolute value and the machine's transverse direction is zero. Set the depth and select the size that needs to be tapped, such as: M5 , The system will give the appropriate speed and feed, and the user can also modify it by himself;
[0064] Step 4:
[0065] When confirming that the parameters are not wrong, press "Start Machining" and the program will clear the axis status. After starting the motion axis, the motion axis moves to the relative position to process the drilling according to the hole size input by the user, and moves to the next hole position after completion , After all the holes are processed, change the taps to convert the coordinates to process the internal thread. After all the taps are completed, return to the main interface.
[0066] Step Five:
[0067] If an accident occurs, press the external stop button urgently.
