step S102, acquiring workpiece processing information of a machine tool where the tool magazine is located.
Since a machine tool is generally used only for mass production of the same product, the procedure for machining the same product is fixed, and the type of tool and the number of tools required are the same.
Therefore, in this embodiment, acquiring the workpiece processing information of the machine tool in which the tool magazine is located includes: reading the use instruction information of the machine tool; workpiece processing information is determined based on the usage specification information.
For example, information on a workpiece that can be processed by the machine tool can be acquired by reading application specification information such as a specification of the machine tool, and processing information on the workpiece that can be processed by the machine tool, such as a machining flow, can be acquired.
And step S104, determining characteristic information of a tool required by the machine tool to machine the preset workpiece based on the workpiece processing information.
In an alternative embodiment, determining characteristic information of a tool required for the machine tool to machine a predetermined workpiece based on the workpiece processing information includes: determining process information for processing a predetermined workpiece based on the workpiece processing information; characteristic information of a tool required for the machine tool to process a predetermined workpiece is determined based on the process information.
That is, in this embodiment, the process information for machining the predetermined workpiece may be determined based on the workpiece processing information, so that the characteristic information of the tool required for machining the predetermined workpiece, for example, the type of the tool, the number of tools, may be determined.
And S106, determining a placing strategy of the needed tool in the tool magazine according to the characteristic information.
In an alternative embodiment, the determining the placement strategy of the required tool in the tool magazine according to the characteristic information comprises: determining the number of cutters of the cutters required for processing the preset workpiece based on the characteristic information; acquiring weight data of each cutter in a plurality of cutters corresponding to the number of cutters; and determining the placing strategies of the plurality of cutters in the cutter base based on the weight data of each cutter.
In this embodiment, the placing mode of the tools in the tool magazine can be determined according to the weight data of the plurality of tools; specifically, the placing strategy of a plurality of cutters in the cutter library is determined based on the weight data of each cutter, and the placing strategy comprises the following steps: arranging the weight data of each cutter in ascending order to obtain a first array; dividing the first array into a first sub-array and a second sub-array; respectively reordering the weight data in the first sub-array and the second sub-array according to data characteristics to obtain a third sub-array and a fourth sub-array; integrating the third sub array and the fourth sub array into a second array; and determining the arrangement sequence of the weight data in the second array as the placing strategy of the plurality of cutters in the tool magazine.
For example, for a plurality of cutters, the weight data of each cutter may be arranged in an ascending order to obtain an initial array, and then the initial array is divided into two arrays, and the two arrays are optimized, so that the cutters are placed in the disc magazine in an arranged manner after the weight data in each array are sorted, and the gravity center of each cutter can be kept near the rotating shaft.
And S108, placing the needed tools in the tool magazine based on the placing strategy.

Therefore, the method for processing the cutters in the tool magazine provided by the embodiment of the invention solves the technical problem that the center of the tool magazine is shifted due to the random arrangement of the cutters with different weights in the tool magazine in the related art, so that the tool magazine is low in reliability.
In an alternative embodiment, placing the desired tool in the magazine based on a placement strategy includes: and placing a plurality of cutters in the cutter base according to the arrangement sequence of the cutters in the weight data of the second array.
Fig. 2 is a flowchart of an alternative processing method for tools in a tool magazine according to an embodiment of the present invention, and as shown in fig. 2, the number n of tools that can be placed in the tool magazine is obtained; sorting the weight data corresponding to the n cutters from small to large to obtain an initial array; dividing the initial array into two groups; acquiring the weight data of the first half, and carrying out numerical optimization on the first n/2 weight data; acquiring the weight data of the second half, and carrying out numerical optimization on the last n/2 weight data; acquiring the optimized front n/2 weight data and rear n/2 weight data; and integrating the optimized front n/2 weight data and the optimized rear n/2 weight data to obtain a target array, so that the placing positions of the cutters on the cutter head are determined according to the weight data in the target array, the cutters are placed according to the sequence, the gravity center of the whole tool magazine can fall near a rotating shaft, the great change of the rotational inertia cannot be caused, and the rotational positioning precision is improved.
It is worth noting that in the actual processing process, a machine tool is generally only used for batch processing production of the same product, so that the program for processing the same product is well fixed, the types and the number of the tools are the same, the machine tool can be arranged on a tool magazine one by one before the first processing, if a blank is formed once, the steps of the machine tool are roughly rough, semi-finish and finish, the rough cutting tool is generally heavier and is suitable for heavy cutting, and the finish cutting tool is relatively lighter and is suitable for high-speed rotary finish milling; if the clamping sequence of the cutters with different weights is not noticed when the cutters are clamped for the first time. Then the cutter head can always bear the condition of uneven gravity center distribution under the ordered cutter changing mode used later, so that the moment of inertia is large during cutter changing, and the service life of the tool magazine and the rotary positioning precision during cutter changing are influenced.
Therefore, in the embodiment of the invention, the distribution of the cutters is optimized, the influence of the cutters with different weights on the gravity center of the tool magazine can be balanced when the cutters are clamped for the first time, and the gravity center of the tool magazine is kept near the rotating shaft. The same arrangement mode is kept in the subsequent ordered tool changing process, and the rotary positioning precision of the tool magazine cannot be influenced.
Assuming that there is a disk magazine of 16 knives, the weight of each knife becomes [1, 1,1, 1,1, 1,1, 1, 1.5, 4.5, 4.5, 5, 5, 7.5, 7.5, 15] in the following code, after sorting from small to large, the value of n in the array is divided into two arrays [1, 1,1, 1,1, 1,1, 1], [1.5, 4.5, 4.5, 5, 5, 7.5, 7.5, 15], the first array is optimized and not changed, the second data set of the optimization result is maintained and optimized to [4.5, 4.5, 5, 7.5, 7.5, 5, 1.5, 15], the arrangement sequence of the two results is [4.5, 1, 4.5, 1, 7.5, 1, 7.5, 1, 5, 1.5, 1,1, 1.5, 1, 15], the arrangement sequence of the knives is set to be [4.5, 1,1, 7.5, 1,1, 1,1, 15], so that the inertia of the whole knife can not change in the rotation axis, the rotational positioning accuracy is improved.
