PDF-Thermal correction - workpiece expansion

AP306 Thermal correction workpiece expansion fT Problem Workpieces can be subject to expansion and contraction owing to thermal effects Variation in temperature of the machining environment or. to expansion". Furthermore, page 14 of the 1997 UL Directory states the following: "Restrained conditions for the fire test assemblies are provided by constructing floor, beam and roof test asse Workshop Technology.

Wuhan, China, Lemily1113@163.com. Abstract —. In this paper, a workpiece detection and positioning system has been studied. Firstly, data sets of workpieces with three different shapes (cube, cylinder and sphere) are established, and the YOLOV3 target detection algorithm is used for deep learning to realize intelligent recognition of different shapes of workpieces. Then by the use of binocular machine vision technology, the key points position of workpieces can be successfully detected with relative error less than 2 %. This workpiece detection and positioning system can be introduced in the mechanical arm grabbing control system to make it has the visual ability similar to human in order to realize mechanical arm intelligent grabbing in complex environment.. 1. = T. 2. . .
