摘要： A system and method for monitoring tool wear in CNC machining operations by monitoring spindle power and extracting instantaneous cutting geometry. The method is based on a physics-based two parameter process model and measuring at two different cutting conditions. The process model parameters are measured with easily accessible spindle power. In contrast to spindle power alone which is influenced by many factors, most especially by variable cutting conditions and by the tool condition, the process model parameters are independent of the geometrically variable cutting conditions and provide a simple and direct measure of tool wear. The two process model parameters change differently depending on the mechanism of the tool wear, specifically flank wear versus cutting edge degradation. This provides a diagnostic for tool wear.

摘要： Replay-time-only functionalities in a computer program are executed only during replay in a virtual machine and are skipped outside of replay. If a replay-time-only functionality is detected during the replay of a program execution in a virtual machine, the replay may be paused and the virtual machine state may be saved. The replay-time-only core functionality is executed. When this execution is complete, a prior state of the virtual machine may be restored and the replay may be resumed.

摘要： A method and system for determining potential deadlock conditions in a target multi-threaded software application. The target application is first run in a virtual machine and the events within the application are recorded. The recorded events are replayed and analyzed to identify potential lock acquisition conflicts occurring between threads of the application. The potential lock acquisition conflicts are identified by analyzing the order in which resource locks are obtained and pairs of resources that have respective locks obtained in different orders are analyzed. These analyzed pairs are used to define a different order of events in the target application that, when the target application is re-run with the second order of events, may trigger a deadlock condition. The target application is then re-run with the different order of events in an attempt to trigger and then identify potential deadlock situations.
