A method, system and computer-usable medium are disclosed for monitoring and controlling a machining process of parts. Data as to dimensions of produced parts are gathered during a production process. The parts are produced based on part control plan. The data of the dimensions are plotted as to statistical information related to a distribution curve. Determination is made if a trend in the dimensional data approaches an upper control limit and a lower control limit. Corrective action is taken if the trend approaches either the upper control limit or the lower control limit.

Unified control system and method for machining of parts

A safety shielded, reusable trocar consisting of a trocar cannula subassembly, a safety shield control mechanism, and a separate obturator subassembly. The trocar cannula subassembly includes an outer cannula attached to a main housing having a central bore in which a spring biased, inner cannula is slidably and removably inserted, and an upper housing, removably secured to the main housing, having a central bore which is aligned longitudinally with the bore of the main housing and in which a seal is removably secured. The obturator subassembly includes an elongated obturator having a replaceable and rotatable knife, an elongated shaft, an arcuate shaped cap, and which extends through the upper housing, seal, main housing, inner cannula, and outer cannula. The safety shield control mechanism, located in the main housing and removably engaged with the inner cannula, allows for positive and easily verifiable engagement and disengagement of the inner cannula as a safety shield for the obturator knife. When the trocar cannula subassembly and safety shield control mechanism are coupled proper operation of the safety shield can be verified without the obturator subassembly being inserted in the inner cannula. In operation, the obturator subassembly, upper housing, and a seal can be completely removed from the trocar assembly to allow unobstructed access through the inner cannula to the patient's internal cavity for removal of specimens or insertion of equipment. After use, the entire trocar assembly can be easily disassembled for cleaning, sterilization, and reuse.
