Definitions

  • the invention relates to a method for operating a machine tool and a machine tool according to the preambles of the independent claims.
  • Panel sizing saws are complex machine tools with a large number of setting options (“operating parameters”). For the efficient operation of the
  • Machine tool and ensuring quality it is crucial that the machine tool or whose parameters are set correctly or and the existing functions of the machine tool and machine control can be used optimally.
  • the correct setting of the machine tool is often not obvious to the operator and therefore requires expert knowledge. Often the operator is not aware of all the available options on his machine and therefore the machine tool cannot be used as efficiently as possible.
  • the manufacturing steps necessary for a workpiece or machining program are specified using so-called “recipes”.
  • the recipe contains the necessary manufacturing steps, but no further settings that are necessary for greater efficiency.
  • the object of the present invention is to improve the operation of a machine tool.
  • the operator based on the operator's respective production situation, intelligent suggestions for improvement are made for optimal use of the machine tool and its options, and the operator is enabled to easily apply these suggestions for improvement in the current production situation.
  • the operator is not “incapacitated” by the control of the machine tool, but can decide based on any expert knowledge he may have whether the suggestion for improvement really makes sense or not.
  • Machine tool in particular a panel dividing system, proposed.
  • the panel dividing system preferably a panel dividing saw, with which large-format panel-shaped initial workpieces are divided into finished workpieces by longitudinal cuts and cross-sections and, if necessary, further cuts, which are used, for example, in furniture production.
  • a panel saw typically includes a feed table, a machine table, a removal table, a sawing device and at least one feed device for moving the workpieces relative to the sawing device or a sawing line defined by the movement of the sawing device.
  • the method according to the invention initially includes step a. the automatic determination of a currently set value of at least one first operating parameter of the machine tool.
  • the value has previously either been set by an automatic control (machine control) based on recorded, determined and/or predetermined parameters, or has been entered manually by the operator, for example based on individual empirical values ("expert knowledge").
  • the method according to the invention also includes step b. an automatic determination of a currently planned production situation of the machine tool.
  • production situation is to be understood rather broadly in the present context and can be any type of parameter or descriptive criterion that that the current editing process as a whole or as such characterized numerically or alphanumerically or describes, and should rather be understood less as a purely numerical value of an individual operating parameter.
  • currently planned means that the production situation should not necessarily exist now, but in the future, i.e. for a future planned production process.
  • a step c. automatically processes the information determined in steps a and b using a data table, which data table links values of the first operating parameter of the machine tool and/or values of a second operating parameter of the machine tool for the currently envisaged production situation with at least one performance parameter.
  • data table also includes a database with values, logical links, exclusion criteria and/or rule sets. The data table therefore contains data sets in which numerical data and/or alphanumeric data can be present.
  • a performance parameter is obtained as a result of the processing , which characterizes the expected performance of the machine tool for the intended production situation and the determined value of the first operating parameter.
  • the method according to the invention comprises in a step d. the attempt to automatically determine, using a data table, at least one alternative value of the first operating parameter of the machine tool or a value of a second operating parameter of the machine tool, which in the currently envisaged production situation leads to a value of the performance parameter that is higher than the value of the performance parameter in the current production situation with the currently set value of the first operating parameter of the machine tool.
  • the search is therefore for a better machine setting than the one currently selected. It goes without saying that there are situations in which there is no more favorable value of the first or a second operating parameter than the currently set values. In this case, the current settings are already optimal. In this respect, the method according to the invention merely “attempts” to determine a more favorable value, but this does not succeed in every case.
  • the two data tables are created in advance.
  • at least the latter data table can also contain explanatory information through which the operator is informed, for example, about the particular advantages of the proposed value.
  • the message may also contain, in particular, the name of the operating parameter and a description of what it means.

L'invention concerne un procédé de fonctionnement d'une machine-outil (10), comprenant les étapes suivantes : a) la détermination automatique d'une valeur actuellement réglée d'au moins un premier paramètre de fonctionnement de la machine-outil (10) ; b) la détermination automatique d'une situation de production actuellement prévue de la machine-outil (10) ; c) le traitement automatique des informations déterminées aux étapes a) et b) à l'aide d'une table de données qui relie des valeurs du premier paramètre de fonctionnement de la machine-outil (10) et/ou des valeurs d'un second paramètre de fonctionnement de la machine-outil (10) pour la situation de production actuellement prévue à au moins un paramètre de performance ; d) la tentative d'utilisation d'une table de données pour déterminer automatiquement au moins une valeur alternative du premier paramètre de fonctionnement de la machine-outil (10) qui, pour la situation de production actuellement prévue, conduit à une valeur d'un paramètre de performance qui est supérieure à la valeur du paramètre de performance dans la situation de production actuellement prévue avec la valeur actuellement définie du premier paramètre de fonctionnement de la machine-outil (10) ; e) si une valeur a pu être déterminée à l'étape d : la fourniture automatique de la valeur alternative déterminée du premier paramètre de fonctionnement de la machine-outil (10) ou de la valeur déterminée du second paramètre de fonctionnement de la machine-outil (10) à une personne.
