In addition to improved alignment accuracy, the process consists of fewer steps than previous mold fabrication process that involves two EBL steps and two pattern transfer steps by etching.
But another machine in the plant, which uses a laser to scan the passing material, can sort plastic by type and colour with great accuracy.This process, says Chris Dow, Closed Loop's managing director, was "a lab trial" two years ago.
These results can validate the accuracy of process simulation.
The voter can check it for accuracy, then process it with an optical-scan machine.
Following the geocoding accuracy measurement process described by Chainey and Ratcliffe 2005.
However, in the accuracy design process of the UPM, the linear errors and angular errors should be independently treated for its higher accuracy target than common machine tools.
Due to the slow speed and low accuracy, the process has not yet been embraced by industry.
It has a noticeable potential to enhance the accuracy of process simulators without sacrificing the simulation time.
Especially, centreless grinding is broadly used in serial production due to the requirement of high accuracy in process.
The models were evaluated in terms of general ease of use, input data requirements and accuracy of process understanding and prediction.
