  • Interruption recovery method for machine tool machining file and machine tool applying same
    Patent number: 11467558
    Abstract: Provided are an interruption recovery method for a machine tool machining file and a machine tool applying the method. The interruption recovery method includes: generating first check information when a machine tool machining file is executed, the machine tool machining file being stored in an external memory; generating second check information when the machine tool machining file is re-executed after an interruption occurs; comparing the first check information and the second check information to determine whether the machine tool machining file is changed before and after the interruption; and recovering the execution of the machine tool machining file when the first check information matches the second check information. By generating and comparing the check information before and after the interruption to verify the integrity and consistency of data of the machine tool machining file, the machine tool machining can be carried out accurately and unerringly.
