ABSTRACT The process of forward cold flow forming is a specific procedure of material processing which is used for forming of different rotationally symmetric parts from cylindrical workpieces placed between the pin and roll in the military, aeronautical, nuclear and other industries. Under the pressure of the rolls (two or three rolls) material is brought to the state of plastic flow and extruded in the axial direction, what results in the reduction of the diameter and increase of the length of workpiece. The deformation of workpiece causes the increase of the heat during the processing. In this paper, the temperature analysis of tubular workpieces Al 99.5 during the processing by cold flow forming is shown. The numerical simulation of the process was carried out using simufact.forming GP 11.0 software. In the next step the results of numerical simulations were experimentally verified by measuring the temperature of heated workpieces during the forming with the help of contactless thermal imaging methods (Thermo-camera Fluke Thermography Series These 32).

Three dimensional measurement of complex geometry with Coordinate measuring machines (CMMs) requires multiple clamping and fixturing of measured object. In order to speed-up this process and to reduce the number of fixturing operations, a robotic arm can be used to manipulate the measured object. This paper describes measurement uncertainty analysis of an improved complex measurement system consisting of robotic arm and the coordinate measuring machine.
