Abstract
A method and apparatus for automatically outputting an operation guidance message. An operation guidance message is output if an operator repeatedly inputs an erroneous command. A processing unit processes a command input by an input unit. An observation unit judges whether an error occurs in the command and compares the number of errors with a constant. An output unit outputs the operation guidance message when the number of errors matches the constant.
Claims10
A numerical control apparatus for operating a machine tool and generating an operation guidance message, comprising:
- input means for inputting a command for operating a machine tool;
- memory means for storing a plurality of programs each of which control an operation of said machine tool;
- observation means for judging whether said command input by said input means is a correct command and outputting a display enable signal when said observation means judges that incorrect commands have been inputted by said input means a predetermined number of times;
- cycle start command means for reading one of said programs stored in said memory means in order to start an operation of said machine tool when said command input by said input means is judged to be correct by said observation means;
- and
- output means for outputting said operation guidance message based on said display enable signal output by said observation means.
A method for operating a machine tool and outputting an operation guidance message in a numerical control apparatus, comprising the steps of:
- inputting an operation command for operating said numerical control apparatus;
- storing a predetermined number, a plurality of programs each of which control an operation of said machine tool and correct command data;
- comparing said operation command to said correct command data in order to determine if said operation command is correct;
- reading one of said programs in order to start an operation of said machine tool when said operation command is determined to be correct;
- issuing an error signal each time said operation command is determined not to be correct;
- counting a number of said error signals;
- comparing said predetermined number to said number of error signals;
- and
- outputting said operation guidance message if said number error signals is greater than said predetermined number.
