Definitions
- the invention relates to a method for processing a workpiece on a machine tool, which can be processed to achieve the same processing result on several possible processing variants.
- a machine tool is understood to be any type of machine tool for machining workpieces, that is to say in particular also a machine tool for machining, for forming or for laser machining of workpieces. So far, the energy consumed in the machining of one or more workpieces on the machine tool can at most be estimated. From the estimated energy consumption, the workpiece-related energy costs can also only estimate and therefore only partially use as the basis for a cost calculation.
- the invention is therefore based on the object optimally optimize or minimize the energy consumed in the processing of one or more workpieces on the machine tool, and to provide a machine tool suitable for this purpose.
- a control unit automatically determines the electrical energy consumption and / or the gas consumption for at least some of the several possible processing variants and automatically selects one of the several possible processing variants for processing on the basis of this determined energy and / or gas consumption,
- the workpiece is processed according to the selected processing variant, and
- the actual electrical energy consumption and / or the actual gas consumption of the selected processing variant automatically be added to the knowledge base.
- the electrical energy and / or the gas supply to the machine tool and thus the energy and / or gas consumption are monitored, e.g. For
- the energy and / or gas consumption of a machine tool can be determined very precisely by part or order, so that a separate gas consumption monitoring can be dispensed with.
- the measured energy and / or gas consumption flows into the knowledge base and will used in the following to select the most efficient processing variant.
- the consumption (power, gas, for example vacuum for vacuum cleaner or compressed air for pneumatics) of automation components is determined separately or additionally by the machine tool itself, so that it can be checked whether it is more efficient to machine or manually disengage the machine - or loaded.
- the acquisition of the consumption values takes place automatically without the intervention of the operating personnel and in particular synchronously with the machining of the workpieces by the machine tool in order to be able to determine an exact workpiece-related energy consumption and from this the workpiece-related energy costs.
- the electrical energy costs incurred during the machining of a workpiece can be determined from the energy consumption values at the beginning and end of the processing, from the current electricity price and possibly also from the number of identical workpieces processed.
- a monitoring of the consumption values also allows a statement about the

- Control unit stored and can be queried by a service employee on site or via the diagnosis by telephone or the Internet.
- the control unit uses the knowledge database to automatically determine the processing time required for the various possible processing variants and automatically selects one of the several possible processing variants for processing on the basis of this determined processing duration, ie, a processing variant with a shortest possible processing time.
- the actual processing time of the selected processing variant is then automatically re-recorded in the knowledge base.
- the control unit automatically for some possible processing variants and the current process duration, ie the sum of machining time, the required replacement time for a tool change and the loading and unloading of the workpiece required loading and unloading, and choose one of the few possible
- the machining variants for machining are also automated on the basis of this determined process duration, ie, for example, a processing variant with the shortest possible process duration. Preference can be given to the possible processing variants:
- control unit automatically compares the few possible processing variants with respect to the costs of their respectively determined energy and / or gas consumption with each other and automatically selects in particular the most cost-effective processing variant for processing.
