Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention is a system for obtaining a predicted condition of an optimal cutting condition of a cutting process, and in particular, an optimal cutting condition prediction system suitable for predicting an optimal cutting condition according to a use environment of an individual user. [0002]
[Prior art]
To perform the cutting, a cutting tool is indispensable, but the conditions for the cutting are various. Cutting tools include indexable inserts, end mills, drills, cutters, etc., which are selected according to the object to be cut, the product shape, and the like. For example, when the indexable insert is selected, first, a tool is selected, and cutting conditions (cutting speed, cutting depth, feed, wet / dry type) corresponding to the tool are selected and processed. Here, when selecting a tool and its cutting conditions, it was common to perform machining with reference to recommended conditions of tools sold by a tool maker.
[0003]
However, since the tool maker only provided general recommended conditions, it was necessary to reconsider the specifications, types, and machining applications of individual users for machine tools.
[0004]
The cutting conditions differ depending on the number, shape, type, and surface treatment of the workpiece to be cut, so that each tool user has optimized each time. Therefore, in the case of a work piece with a small working record, it is necessary for the working person to set cutting conditions assumed empirically and to find the optimum working conditions, which requires a great deal of time.
In addition, since these optimal processing conditions are know-how for each worker, there are variations in the optimal conditions even within the same factory, resulting in a problem of inefficiency.
[0005]
In order to efficiently perform these optimizations, tool manufacturers provide information so that they can select tools according to the work material, machining shape, etc. Figures, tables, etc. were provided so that they could be used. Furthermore, in recent years, as an electronic catalog system (for example, see Patent Document 1), when a user inputs conditions of a workpiece to be processed, a tool recommended by a tool maker and recommended cutting conditions have been selected. .

[Problems to be solved by the invention]
In the prior art, a tool maker provides a selection of a tool and a cutting condition according to the tool, but these are conditions recommended by the tool maker in order to maximize the life of the tool. However, depending on the user, there are many cases in which a sufficient cutting speed cannot be obtained due to insufficient power of the machine tool, and restrictions on work mounting. For that purpose, it is necessary for individual users to again seek the optimum cutting conditions according to their environment. Furthermore, these mismatches differ greatly in the time required to optimize the cutting conditions depending on the skill of the operator. Therefore, it has been required to efficiently obtain optimum cutting conditions for each cutting environment.
[0008]

An optimum cutting condition prediction program for functioning as a means for correcting the cutting prediction condition 1 and obtaining the cutting prediction condition 2 based on the recording of the cutting prediction condition 1 and the recommended processing condition record. However, individual users can predict the optimal cutting conditions for the environment in which the cutting tool will be used, and make corrections with the tool manufacturer's recommended conditions, thereby enabling highly accurate prediction of optimal cutting conditions. It is.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a flow obtained by executing the system of the present invention.
[0011]
First, data on optimum cutting conditions, which have been examined variously, are input. As shown in FIG. 2, the input is entered in a predetermined cutting data sheet. The cutting data is used to collectively input a machine to be used, a work as a work material, a tool, cutting conditions, results, and the like. For the machine to be used, enter the machine name, the person in charge, and the type of machine. In the work, a cutting style such as a part name, a work material name / material, hardness, continuous / intermittent or outer / inner diameter machining is input. For the tool, a selection condition, a tool material type, and a shape / dimension (for example, a chip model number) are input. For the cutting conditions, the type of cutting oil, cutting speed, number of revolutions, processing diameter, feed, and depth of cut are input. For the test results, enter conclusions (good, bad, unchanged), machining quantities (conventional and present), causes of tool life, and other information. Furthermore, supplementary items can be entered. Input This data can be deleted, for example, when better cutting conditions are obtained afterwards.
[0012]
The input cutting condition data is recorded as a cutting condition list. FIG. 3 is a list of recorded cutting performance data. The date and time when the data was entered and the contents entered can be listed.
[0013]
FIG. 4 shows that at the time of newly optimizing the cutting processing conditions, at least one of an object to be processed (work material, processed shape, physical property value, etc.) and a processing method (outer processing, inner diameter processing, grooving, etc.) Enter one condition.
The input conditions are compared with the processing result data record, and the cutting condition prediction condition and the prediction condition relating to the tool and the machine to be used are obtained from more approximate conditions.
[0014]
The conditions shown here provide cutting conditions predicted from the optimum conditions according to the processing environment of the system inputter of the present invention, and optimization by individual users can be achieved more than the recommended conditions provided by the tool manufacturer. The obtained cutting conditions are obtained.
[0015]
Although such a system can provide cutting conditions optimized by individual users, if the tool is unknown, the reliability of the conventional data as it is becomes low as basic data for prediction. Therefore, the inventor has found that when an unknown tool is used, the prediction accuracy can be improved by supplementing the data with the tool manufacturer's recommended data.
[0016]
Specifically, as shown in FIG. 5, after the above-mentioned optimum cutting condition prediction 1 is obtained, a difference between the processing condition of the tool used in the cutting condition and the recommended condition of the tool maker is calculated. Therefore, by subtracting the above-mentioned difference from the recommended condition of the tool manufacturer of the unknown tool, highly accurate prediction 2 can be obtained as the optimum condition for the usage environment of each user.
The recommended condition of the tool maker is a catalog format, and a conventional electronic catalog in which the recommended condition of the tool is electronic data can be used.
[0017]
As described above, the description of the present invention has been made in detail for the case where the present invention is implemented by a personal computer, but the embodiment is not limited to this mode. For example, a database can be constructed on the Internet, and a user can use individual data by computer operation. As an electronic medium for recording the system of the present invention, a CD-ROM, a DVD, a hard disk, or the like can be used.
[0018]
【The invention's effect】
The present invention has made it possible for individual users of the cutting tool to determine the optimal cutting conditions according to the individual use environment. Furthermore, it became clear that the time required for optimizing the cutting conditions was greatly reduced depending on the skill level of each user and the optimum cutting conditions for each cutting environment could be efficiently obtained.
