An online geometric/thermal error measurement and compensation system for computer numerically controlled (CNC) machine tools belonging to the technical field of error testing and compensation of CNC machine tools. The online CNC machine tool geometric/thermal error measurement and compensation system includes two parts: the hardware platform and the measurement and compensation software. The hardware platform includes a unidirectional acceleration sensor, a precision integrated circuit (IC) temperature sensor, a multi-channel temperature data collector, and a geometric/thermal error measurement and compensation host. The error measurement and compensation software runs in the geometric/thermal error measurement and compensation host and realizes testing and compensation of geometric and thermal errors in machine tools, which are communicated to the FANUC CNC system. The invention belongs to the technical field of error testing and compensation of computer numerically controlled (CNC) machine tools and is specifically a linear measurement and compensation system for measuring and compensating for geometrical/thermal errors in CNC machine tools.Errors of CNC machine tools mainly include geometric error, thermal error, control error, and force error. Among these, geometric and thermal errors will have the largest impact on the machine tool. Geometric errors not only affect positional accuracy, but also affect accuracy of the curve. Thermal errors influence positional accuracy as well as stability of the CNC machine tool. In order to reduce the influence of geometric and thennal errors on machining accuracy of CNC machine tools, measures should be taken to improve assembly precision. For this, full closed-loop control is generally adopted along with controlled cooling rates. Although these measures have some effect, they also increase the cost of machine tools. The error compensation technique can effectively reduce geometric errors and thermal errors at a lower cost. ...

The present disclosure relates to methods and systems for selection of synchronization targets. Embodiments of the present disclosure provide for selecting a synchronization target for a network device, within operational network constraints, when the network device loses its current synchronization target. When a network device loses its current synchronization target, the stratum index of the network device is downgraded to an artificial stratum index before a selection of a new synchronization target is made. The artificial stratum index is broadcast to children network devices. Downgrading the stratum index to an artificial stratum index allows for selection of available synchronization target network devices with stratum indices higher than or equal to the network device's stratum index. After selection of a new synchronization target, the network device's stratum index is updated, and the new updated stratum index of the network device is broadcast to the children network devices of the network device. 1.
