Abstract: In a machine tool which executes a plurality of programs simultaneously to perform machining, whether or not a precision machining operation period exists in each of the programs is analyzed before machining. If the precision machining operation period exists as a result of the analysis, the start timing and end timing of an ordered precision machining is recognized. Also, at least one of the speed, acceleration, and jerk of a general operation from start timing to end timing in a program for which the precision machining operation period is not specified is lowered. Accordingly, it is possible to provide a machine tool and its program conversion method, capable of performing precision machining with high precision without receiving an adverse effect from other operations, and capable of obtaining good machining efficiency.

Abstract: [Problem]To provide a numerical control apparatus of a machine tool and a numerical control method of a machine tool capable of increasing a conversion ratio of the case of converting an NC program into an electronic cam program and improving working efficiency by eliminating the need to cut off electronic cam data before and after an S code or an M code.

Abstract: The present invention provides a numerically controlled machine tool and a program transforming method therefor where a NC program is transformed into an optimum program even by a non-expert programmer. Particularly, the present invention provides a method for optimizing a NC program for operating a numerically controlled machine tool, comprising: making the NC program to be loaded into the numerically controlled machine tool; designating a portion of the NC program to be determined whether it is transformable and/or a portion of the NC program to be determined whether a command position is changeable; storing the NC program in a memory; determining whether the designated portion is transformable and/or whether the designated command position is changeable; and transforming the designated portion and/or changing the designated command position, and making an operating program file for the numerically controlled machine tool.

Abstract: A numerical control apparatus for machine tool, includes an NC program storage portion for storing an NC program; a transformer means for performing an optimizing process for analyzing the NC program and parameters in the machine tool and transforming the NC program in an optimum condition; an optimized program generated by said transformer means and containing an optimized main program, and optimized data; first and second optimized data storage portions for storing and holding the optimized data. While the machine tool is operated according to the optimized program on the basis of the optimized data stored in the first optimized data storage portion, the transformer means can generate new optimized data on the basis of the NC program and can write a transformed data in the second optimized data storage portions.
