METHOD AND DEVICE FOR OPTIMIZING THE OCCUPANCY OF MAGAZINE SPACES BY TOOLS IN A COMPUTER-SUPPORTED MANNER

摘要

The invention relates to a method for optimizing the occupancy of magazine spaces (P) by tools within at least one tool magazine (R) for a machine tool in a computer-supported manner. One or more workpieces of one or more workpiece types is produced using the tools supplied by a magazine device at a supply area, having the following steps: a) detecting a number of workpieces to be produced, b) detecting a number of magazine spaces (P) in at least one tool magazine (R), c) detecting a number of tools, d) detecting the required space and optionally at least one other property for each tool, e) detecting allowable magazines spaces for each tool, an allowable magazine space depending on the required space, the other property of the tool, and/or a detected property of the magazine space, f) detecting an allowable starting magazine occupancy, a starting magazine space for each tool being detected, g) detecting a sequence of work steps to be carried out by the machine tool on a workpiece, wherein a tool provided for a work step of the sequence is used to produce the workpiece, h) detecting work step time periods required to carry out each individual work step on the workpiece, i) detecting one or more supply time periods depending on the sequence of the work steps to be carried out and depending on a magazine occupancy required for supplying the respective tool for the following work step at the supply area by means of the magazine tool, j) optimizing the occupancy of the magazine spaces by tools, each of which can occupy only one allowable magazine space in a collision-free manner such that the entire wait time is minimized, said entire wait time being composed of individual wait times resulting from the respective difference between the detected supply time period and the detected work step time period if the value of the difference is positive, otherwise the individual wait time assumes the value of null. The invention is characterized in that k) the occupancy of the magazine spaces by tools is optimized such that said tools are placed on the same magazine spaces of the starting magazine occupancy or on allowable magazine spaces near the magazine space previously occupied by said tools in a collision-free manner.
