When the required tool does not correspond to the standard tool magazine information, the control software can automatically give an early warning, and an operator can perform manual intervention;
the control software automatically calls the on-machine measuring head to touch the workpiece shape of the processing coordinate specified in the previous step, and the touch result is automatically recorded in the background database (the operation supports manual output of related results/automatic input of external height ruler results). After the appearance of the workpiece is measured, the control software automatically calculates whether the size of the workpiece is matched with data required by task processing, abnormal automatic early warning is realized, and an operator can perform manual intervention;
the control software automatically lists the information of the tool list required by the batch of workpieces, and the operator can confirm the information again;
the processing program set is automatically processed and automatically executed.
The process is carried out as follows:
and according to the configuration of the background database, the numerical control equipment automatically confirms the tool setting of the tool. The actual cutter information is not matched with the cutter information in the processing task, the equipment automatically warns and stops processing to prevent abnormal processing;
according to the configuration of the background database, preheating is carried out for a certain time after all the cutters are transferred into the main shaft from the equipment tool magazine, so that the cutter setting operation is carried out after the main shaft reaches the expansion limit, and the machining precision of the workpiece is ensured;
after each cutter is machined, the cutter is automatically confirmed, the abrasion of the cutter is automatically judged, the system automatically records and gives an early warning when the abrasion exceeds a critical value, and the equipment stops machining so as to prevent machining abnormity.
In the whole processing process, the control software records and writes information such as the running state of the equipment, the spindle load, the execution content of a processing program group, the processing time of a tool, an abnormal alarm and the like into a log file, provides a special statistical analysis page, an operator/manager can check the running condition of the equipment and analyze data at any time, and provides rich main stream interfaces for other automatic systems/internet of things systems to collect and integrate and analyze related data.
According to the scheme, through a standardized operation flow and a data form, control software is integrated in the numerical control equipment, a special operation interface is provided for interaction with an operator, the operator only needs to appoint each processing coordinate (which can be determined through a preset position of a clamped workpiece) and a corresponding data folder in which a processing program and a program list are stored on a control panel of the numerical control equipment, the control software can automatically calculate the matching relation between a configuration file of a background database and the workpiece to be processed, then automatically call related configuration hardware of the equipment to process and check the appearance of the workpiece and a numerical control cutter, and finally drive the numerical control equipment to automatically process the workpiece. And in the machining process, the control software monitors the running condition of the numerical control equipment in real time, and if the machining is abnormal, the early warning is automatically carried out and related personnel are informed. The control software can automatically record all processing related log files in the background during the operation period and automatically generate related statistical reports for the checking of managers; meanwhile, related data ports are opened to carry out data seamless butt joint on the automation/Internet of things and other related systems.
The scheme can reduce the dependence on an operator to the lowest possible degree, greatly reduce the man-machine ratio, ensure that the utilization rate of numerical control equipment can reach more than 95 percent, reduce the processing accident rate caused by human factors to be less than 5 percent, ensure that a manager can know the conditions of the operator, the numerical control equipment, a workpiece, a method and the environment in real time and provide basic data and an interface for the deep internet of things of the mechanical processing industry.
