Abstract
A method and apparatus for managing tow end placement. A time at which movement of a tow is initiated or stopped during a layup process is detected. A latency between the time and a command time corresponding to a command to begin movement or stop movement of the tow is determined. A determination is made as to whether the latency is within a desired range. A timing offset used by a control system that controls tow layup is adjusted in response to a determination that the latency is not within the desired range.
Claims28
A method for managing tow end placement, the method comprising:
- detecting a start time at which movement of a tow is initiated for a layup process;
- determining a start latency between the start time and a start command time at which a start command to begin movement of the tow is received;
- determining whether the start latency is within a desired range;
- and
- adjusting a start timing offset used by a control system that controls tow layup in response to a determination that the start latency is not within the desired range.
A method for managing tow end placement, the method comprising:
- detecting a stop time at which movement of a tow is halted for a layup process;
- determining a stop latency between the stop time and a stop command time at which a stop command to halt movement of the tow is received;
- determining whether the stop latency is within a desired range;
- and
- adjusting a stop timing offset used by a control system that controls tow layup in response to a determination that the stop latency is not within the desired range.
An apparatus for verifying tow end placement, the apparatus comprising:
- a sensor system that detects a start time at which movement of a tow is initiated for a layup process;
- and
- a control system that determines a start latency between the start time and a start command time at which a start command to begin movement of the tow is received;
- determines whether the start latency is within a desired range;
- and adjusts a start timing offset used by the control system in response to a determination that the start latency is not within the desired range.
