ABSTRACT:
TECHNICAL FIELD
The present invention relates to a support system for a laser beam machine, and a laser beam machine including the support system.
BACKGROUND ART
In a conventional control system for a laser beam machine, an operator examines a state or result of the processing after trial laser processing is performed, and, if the processing is incomplete or unsatisfactory, the operator determines a processing condition(s) or processing condition parameter(s) (such as machining speed, peak output, duty ratio, and frequency) which should be changed, and an estimates amount of change of each parameter, based on the result of the examination. Then, another trial processing is carried out based on the estimation, and this procedure is repeated until a desirable cutting result is achieved.
The operator, however, needs to be highly skilled or have enough knowledge to determine which processing condition(s), out of numerous processing conditions, should be changed, and what amount of change needs to be made to each processing condition parameter. It takes some time even for a skilled operator to appropriately change values of the processing conditions. It is therefore an object of the present invention to provide a support system for a laser beam machine, which enables an operator to easily change or adjust the processing conditions depending upon the processing state, and provide a laser beam machine including such a support system.
DISCLOSURE OF INVENTION
To accomplish the above object, the present invention provides a support system for a laser beam machine, which includes an inferred value production unit which produces an inferred value (or estimation value) for each of a plurality of processing condition parameters including a laser beam speed and a laser output, while utilizing an artificial intelligence function, and a display unit which displays the inferred value produced by the inferred value production unit.
In the support system constructed as described above, the inferred value for each of the processing conditions to be changed are produced with the artificial intelligence function, so that the final processing conditions can be easily determined by referring to the inferred or estimated values.
The above-described inferred value production unit may include a processing condition parameter selecting means for selecting one of the processing condition parameters which is most effective to modify the current processing state, based on the evaluation parameters entered through a suitable input means, and a inferred value calculating means for calculating the inferred value based on the most effective processing condition parameter selected by said processing condition parameter selecting means, and the evaluation parameters entered by a input means.
With this arrangement, the most suitable inferred values for the processing parameter(s) can be quickly obtained.
Preferably, the inferred value calculating portion includes a second table means used for calculating the inferred value based on the input parameters (such as the evaluation parameters and the most effective processing parameters). The inferred value producing unit includes a table modifying portion which modifies the second table means in accordance with a current inferred value and a previous inferred value. With this arrangement, the accuracy of the second table means is improved, and therefore the number of operations for correcting the processing conditions can be reduced.
The support system may include a process guidance screen generating means for generating a process guidance screen which includes a processing condition parameter search guidance table that represents the relationship between each of poor processing phenomena observed as a result of laser processing, and each of a plurality of processing condition parameters indicative of conditions under which laser processing is performed. By referring to the guidance table, the process condition parameters can be easily changed or modified.
