Definitions
- the invention relates to a monitoring system and to a method with a monitoring system which is used as standard for process-accompanying monitoring of tools, workpieces or machining processes in metal-cutting machine tools.
- Such machine tool components are essentially those that perform movements in the machine tools. They are therefore essentially limited to feed slides, tool and workpiece spindles, but also to units for the further operation of a cutting machine tool.
- the method according to the invention makes it possible to save separate monitoring devices for the monitoring or checking of feed slides and tool or workpiece spindles, as a result of which a significant cost Potential savings result because hardware, software, control panel and interface to the machine control can not be duplicated.
- vibration sensors are attached to the spindle housings near the bearings on machine tools for checking bearing damage and the cables of the sensors are routed to accessible plugs on the front of the machine tool.
- the maintenance staff uses these plugs to analyze the signals for bearing damage from time to time with analyzers. For this purpose, the signals are recorded with the analysis devices and later analyzed offline. There is no in-process monitoring.
- Monitoring systems for process-accompanying monitoring of tools, workpieces or machining processes in metal-cutting machine tools for turning, drilling or milling have the goal of detecting at least one of the conditions of tool breakage, tool breakout, tool wear, tool for workpiece contact, chattering or machine collisions in-process and in particular in the event of tool breakage or Machine collision to shut down the machine drives as quickly as possible to avoid consequential damage.
- Such in-process monitoring systems already have an electrical interface between the monitoring system and the machine control in order to monitor the signal curves of the sensors in-process in monitoring sections specified by the machine control and in the event of detection one of the above states to shut down the machine via the same interface.
- the interfaces between the machine tool control and the monitoring system were previously essentially in the form of parallel input and output signals to the PLC control.
- Such a parallel interface between the PLC and a tool and process monitoring system exists, for example, according to the BAPSI standard, which already allows data words to be transferred as tool code or cutting code from the NC program to the monitoring system.
- PLC programmable logic controller
- the invention has for its object to provide a monitoring system and a method for process monitoring of machine tool components that can monitor or check components of machine tools without significant changes to the hardware or software of the monitoring system.
- a monitoring system for machine tool components For the detection, monitoring or checking of faulty conditions on components of machine tools such as damage or wear on the feed carriage, on the tool or workpiece spindles or the imbalance on tool or workpiece spindles or on drilling or milling tools, in that both solved Tasks with one and the same monitoring hardware with corresponding evaluation software and one and the same bidirectional interface, preferably a fieldbus interface, between the monitoring hardware and the machine control realis be. Only additional sensors are used on the machine tool components, the feed slide or the tool or workpiece spindles if these were not necessary for the causal process-related monitoring task on tools, workpieces or machining processes.
- monitoring thresholds and monitoring or evaluation strategies of known and arbitrary types such as static thresholds, dynamic thresholds, thresholds of signal pattern curves, working value thresholds, etc. are standard today . exist, just as they are also necessary for the monitoring of faulty conditions on components of machine tools.
- the invention solves the problem of when and how the machine control has to act as a controlling component for the monitoring sections for the detection of the faulty conditions on components of machine tools and whether or how they may be used to generate corresponding signals at the sensors of the machine tool component Feed carriage or the tool or workpiece spindle moves, moves or rotates.
- a process-accompanying monitoring system for monitoring tools, workpieces or machining processes in cutting machine tools for turning, drilling and milling can also recognize, monitor or specifically check faulty conditions on components of machine tools. Additional sensors can be present on the components of machine tools, to which the monitoring system can automatically switch depending on the monitoring section selected by the control.
- Claims 13-25 describe and claim how the monitoring system can detect, monitor or specifically inspect damage or wear on tool or workpiece spindles.
- Claims 26-32 claim and describe how the monitoring system can detect, monitor or specifically check the imbalance on tool or workpiece spindles.
- Claims 33-35 claim and describe how the monitoring system can detect, monitor or specifically check the imbalance on drilling or milling tools.
- Claims 36-42 claim and describe how the monitoring system can detect or monitor damage or wear and tear on other units required for operating the machine tool, or can check them in a targeted manner.
