Abstract
An operational monitoring system for use with a liquid jet cutting system can include an accelerometer coupled to a cutting head of the liquid jet cutting system. The accelerometer can be configured to generate motion data associated with movement of the cutting head. The system can include a computing device operably connected to the accelerometer and having a memory and a processor. The memory can store a planned data set including expected parameters associated with movement of the cutting head along a planned cut path. In some embodiments, the computing device is configured to receive the motion data from the accelerometer and correlate the motion data to the planned data set.
Claims20
A method of monitoring operation of a liquid jet cutting system with a computing device, the method comprising:
- receiving motion data at the computing device, wherein the motion data is generated by an accelerometer and indicates movement of a cutting head of the liquid jet cutting system;
- comparing the motion data to planned data, wherein the planned data reflects normal operating motions and/or normal operating conditions associated with a planned cut;
- and
- indicating a condition of the liquid jet cutting system based at least in part on the comparison of the motion data to the planned data.
A method of monitoring operation of a liquid jet cutting system with a computing device, the method comprising:
- receiving motion data and characteristic data, wherein the motion data is received from an accelerometer and is associated with movement of a component of the liquid jet cutting system, and wherein the characteristic data is received from a sensor and is associated with one or more performance characteristics of the liquid jet cutting system;
- comparing the motion data to the characteristic data;
- and
- determining whether a failure has occurred within the liquid jet cutting system based at least in part on the comparison of the motion data to the characteristic data.
