Abstract
The invention relates to a method for operating at least one machining apparatus as well as a machining system with at least one machining apparatus. Such a machining apparatus can be a machining apparatus for machining workpieces, in particular panel-shaped workpieces, which are used, for example, in the furniture and component industry.
Claims15
A method for operating at least one machining apparatus (10, 10′), comprising the steps of:
- machining a first workpiece with a plurality of machining units (13, 13′, 13″) such that the workpiece has a profile at least in portions,
- determining an actual profile geometry of the machined workpiece,
- comparing the actual profile geometry to a target profile geometry,
- and, if a deviation of the actual profile geometry over the target profile geometry is determined, outputting at least a corrective value for at least one of the machining units (13, 13′, 13″).
The method according to one of the preceding claims, characterized in that partial corrective values for a respective machining unit (13, 13′, 13″) are determined as a corrective value after determination of a deviation between the actual profile geometry and the target profile geometry, and the respective partial corrective value is output to the respective machining unit (13, 13′, 13″).
The method according to one of the preceding claims, characterized in that the at least one corrective value comprises a displacement movement of one of the machining units (13, 13′, 13″) in at least one translational direction and/or at least one rotational direction, preferably in a plurality of translational and/or rotational directions.
The method according to one of the preceding claims, characterized in that the method is carried out, in particular sporadically, cyclically or continuously, during a manufacturing process or the method is carried out during a set-up process.
The method according to one of the preceding claims, characterized in that the determination of the actual profile geometry is undertaken by means of at least one contactless measuring apparatus (30), in particular a camera, a laser and/or an ultrasonic measuring apparatus, the determination of the actual profile geometry being preferably carried out by means of an impinging light method or transmitted light method from one side of the profile.
The method according to one of the preceding claims, characterized in that the determination of the actual profile geometry is carried out by means of a measuring apparatus (30′) comprising one or a plurality of contact sensors (31′, 32′).
The method according to one of the preceding claims, characterized in that after the output of a corrective value at least one further workpiece is machined and the step of determining an actual profile geometry and comparing the actual profile geometry with a target profile geometry is repeated.
The method according to one of the preceding claims, characterized in that the machining of the workpiece can comprise a machining process, in particular a milling process, a drilling process, a grinding process or a combination thereof.
The method according to one of the preceding claims, characterized in that a plurality of machining apparatus of a machining system (1) are operated with this method.
A machining system (1), in particular for machining a workpiece of wood or wood materials, comprising at least one machining apparatus (10, 10′), the machining apparatus (10, 10′) comprising a plurality of machining units suitable for forming a profile on a workpiece, further comprising:
- a measuring apparatus (30, 30′) configured to determine an actual profile geometry of the machined workpiece, and
- a control (20) configured to compare the actual profile geometry with a target profile geometry.
