| 20100241267 | APPARATUS FOR AND METHOD OF MEASURING WORKPIECE ON MACHINE TOOL - A workpiece measuring apparatus includes a programmable controller which acquires positional data of a measuring head. At the same time that the programmable controller acquires the positional data, a pulse output unit outputs timing pulses. The measuring head measures a workpiece on a machine tool according to a measurement command which is output positively earlier than the timing of predetermined time intervals by a time difference which is preset by a predictive system. As a result, a first time at which the programmable controller acquires the positional data of the measuring head and a second time at which the measuring head measures the workpiece in response to the measurement command synchronize. The workpiece measuring apparatus is capable of measuring the workpiece highly accurately in a three-dimensional space according to a minimum required amount of measured data without the need for modifying an existing NC apparatus combined with the machine tool. | 09-23-2010 |
| 20110106292 | Method and System for Measuring the Dynamic Response of a Structure During a Machining Process - A machine implement includes sensors that measure a force imparted by the machine implement to a structure during a machining process. A sensor array coupled to the structure measures the vibrational response of the structure to the imparted force. Analysis software compares the imparted force to the vibrational response to generate a transfer function for the structure. Based on the transfer function, a tool-path of the machine implement may be adjusted such that the resulting structure has precise vibrational characteristics that substantially comply with a set of design goals for the structure. | 05-05-2011 |
