How does a CNC lathe work?

1, CNC lathe in the production of parts before processing, according to the design and analysis of the process plan of the machined parts, and then programming. Should be the first preparation of the work of the processing process, if the workpiece processing program is long and particularly complex, try not to program on the machine tool, you can use programming machine programming or manual programming, so as to avoid the occupation of time, and for the program is short, should also be written in the program list.

2, for the input of the processing program, you can choose the interface of the computer and CNC lathe for direct communication, the preparation of parts of the processing program input to the CNC system. Then also need to pre-adjust the tool and fixture, according to the parts of the processing process design to determine the tool and fixture program, before processing parts, install and adjust the tool and fixture. Then the NUMERICAL control device for processing procedures for decoding and operation processing, processing will become a pulse signal, will be sent to the servo system of the lathe, and then through the transmission mechanism to drive the relevant parts of the machine tool, complete the cutting and processing of parts. There will be sent to the programmable controller, in accordance with the order to control the other auxiliary parts of the machine tool, so as to complete the workpiece clamping, loosening, coolant opening and closing, automatic replacement of tools and other actions. About the key points of clamping can refer to the six points of nc lathe clamping attention.

3, the process of starting CNC lathe is to start the machine tool first, and then start the system. Because some designs are interlocked, the machine tool can not display the corresponding information on the CRT without power. Turning reference point, for the incremental control system of CNC lathes, must be implemented this step, the establishment of the machine tool coordinates of the movement standard.

4, for the input program if you need to modify, then you need to edit the operation. At this point, place the mode selector switch in the EDIT position and use the EDIT key to add, delete, change, etc. If the CNC lathe is locked, the program needs to be checked, and if errors are found, it needs to be re-edited.

5, and then on the workpiece, find knife to knife operation, choose manual incremental movement, continuous movement or the use of hand sowing disk moving lathe. Point the tool to the starting point of the program and check the tool reference.

6, start the coordinate feed, continuous processing of parts, usually using the program in memory processing, for this way than using the program on paper tape processing failure rate is lower. Feed rate can be switched to adjust the feed speed in machining. In the process of processing, the FEEDHOLD button, also known as FEEDHOLD, can be pressed to suspend the feed movement and observe the processing situation or make manual measurement. Once finished, the CYCLESTART button is pressed to resume the job. To ensure that the process is free of errors, a careful review is required before processing. For the plane curve of the workpiece processing, you can use a pencil to replace the tool on paper to draw the outline of the work piece, so you can see intuitively, if the system has tool trajectory simulation function, you can use it to check the program is correct or not.

7, CRT can display each screen display table or tool position, program and CNC lathe status information, so convenient for operators to monitor the processing process. When the program is finished, if the program needs to be saved, it can be left in the MEMORY of CNC. If the program is long, it can be saved by external devices.

8, for parts detection and dismantling operations, in the case of the workpiece is still in the chuck clamping, workpiece size detection, if the size of the workpiece is not qualified, the need to carry out appropriate tool compensation operations, new processing, when the size of the workpiece is qualified. After the completion of all process operations, shutdown, shutdown is also the first to close the CNC lathe, and then the system.
