Method of detection of shape- stability of shaped wood material-presing

摘要

Method which is characterised by case detection characteristics shaped-stability of shaped arched material is radius of curvature of shaped material and his changing, whereby radius of curvature of shaped pressed material is detected by preparation for measuring polar co-ordinates of points of shaped material that are transformed to cartesian. On the ground of cartesian system with evaluation by non-linear regression, the radius of curvature of shaped material is obtained during time of stabilisation.
