Abstract
A method for creating machining conditions and/or machining condition series capable of meeting a plurality of required machining specifications, in which the method designates at least one of ranges of the machining specifications, ranges of satisfaction degrees for the required specifications and functions indicating satisfaction degrees to the required specifications. The method determines a compromise between the required machining specifications. The required machining specifications includes surface roughness, consumption rate of the electrode and machining time.
Claims11
A method of automatically generating machining condition series meeting a plurality of required machining specifications, said machine condition series being used at least as operating parameters for a machine tool, the method comprising the steps of:
- designating ranges for the machining specifications including required values of said machining specifications, and satisfaction degree functions indicating satisfaction degrees relating to user desirability of said specifications within said ranges;
- constructing a number of machining steps realizing values in said ranges for at least one type of said machining specifications;
- selecting machining conditions realizing said steps, respectively, from previously stored data of machining conditions;
- enumerating all combinations of the selected machining conditions, as machining series, said combinations each being capable of realizing values in said ranges, respectively;
- calculating total satisfaction degrees with respect to said machining condition series, respectively, by multiplying said satisfaction degrees by one another relative to specifications which are met by each said machining condition series, in which each said satisfaction degree is obtained from said functions based on the value of each specification as met by each said machining condition series;
- and
- selecting a machining condition series having a high total satisfaction degree.
A method of automatically generating machining condition series meeting a plurality of required machining specifications, said machine condition series being used as parameters for operating a machine, the method comprising the steps of:
- designating ranges of the machining specifications including required values of said machining specifications;
- designating a satisfaction degree function for each of said ranges of machining specifications, wherein said satisfaction degree functions indicate the desirability of the values within said ranges of machining specifications;
- constructing a number of machining steps realizing values in said ranges for at least one kind of said machining specifications;
- selecting machining conditions realizing said steps, respectively, from previously stored data of machining conditions;
- enumerating all combinations of the selected machining conditions, as machining condition series, said combinations being capable of realizing a plurality of values in said ranges, respectively;
- and
- selecting machining condition series based on said satisfaction degree functions.
