The preparation work includes the initialization of the system self-test system, and the detection object is mainly the travel switch display, the indicator numerical control panel, the operation panel, and the like. Initialization is mainly to set the initial state of the system, such as setting the interrupt vector, working register status, stack position, and latch clearing. The non-working status of the background program 1 preparation method has four choices, including program input, preparation processing, result output and shutdown; processing mode selection is mainly manual, cyclic, single-segment operation and dry run, or use the keyboard to set parameters, so that The machine returns to the origin of the milling machine or the specified reference point.
The background program in the working state refers to the cyclic program of the system when the milling machine is working. Not only the processing data, standard and position instructions are latched, but also the length of the program. Because this program is closely linked to real-time control, the timing matching between the background program runtime and the timed interrupt must be considered. Determine whether the processing is finished, if yes, exit the background program in the working state, and also respond to the interpolation interrupt program and the servo control interrupt program, and execute the display display program, mainly displaying the current information of the machining block, graphics and NC, PC. Interrupt service programs such as the processing location include the tape drive interrupt service program, the keyboard interrupt service program, and the power-down protection interrupt service program. The main control requirements of CNC machine tools are 1 manual and automatic mode selection; realize the speed control of the main motor (drive milling cutter) MI, the motor is regulated by the frequency converter. The sequence control requires that the motor can rotate in the forward and reverse directions. It can be started after the two lubrication station motors (M4, M7) are started first, and the M7 and M4 can be stopped after stopping. The chip cooling motor MS cooling pump motor M6 can only be started after Ml is started, and can be stopped after Ml stops. (Finish)
C, Z shape roll forming machine and C&Z interchangeable roll forming machine. C purline, Z purline, H beam and others are used for big house building. They are the frame of the house. Normally speaking, the thickness of the material is between 1.5-3.0mm. So for the roll forming machine, it has high standard requirements." It can be widely used in the large and medium-sized enterprise civil construction, such as plant,warehouse,locomotive shed,hanger,exhibition,theatre,stadium and so on.
