“…Thus, setting of the CNC control system parameters with respect to the interaction between the feed drive control and the machine tool structure plays an important role in achieving high productivity and quality of the machining process. The concept of virtual production was presented during the 1990's [Onosato 1993], [Iwata 1995]. These concepts were at the manufacturing system level.…”

Five-axis finish milling is a complex process. The requested surface quality and accuracy must be produced in the shortest possible time. The three main process characteristics-quality, accuracy and machining time-are closely related one to each other. They are affected by the dynamic properties of the machine tool structure, the feed drive properties including cascade control, the control system interpolator properties and the NC code. Thus the appropriate optimization of all related parameters throughout the entire chain is demanding in terms of both time and material. This paper describes the creation of a virtual machine tool that takes into account the properties of the machine structure, feed drives and their cascade control. This machine tool model is connected to the CNC control system kernel. Tests used to verify control system functionality are presented. A virtual simulation of the process is demonstrated on the use case. The process chain parameters are optimized using the virtual machine tool to increase productivity. The simulation and experimental results are compared.

The machining process of Blisk blades poses multiple challenges due to high requirements on surface quality and precision combined with high dynamic compliance of the thin-walled blades. Avoidance of chatter is thus of high priority in Blisk blade machining. However, the geometry of the Blisk blade array where the tool must fit between individual blades significantly limits the possibilities of controlling stability through the relative orientation of the tool and workpiece. Thus, the main parameters that can be used to control the stability of the process are the distribution of stock allowance and the spindle speed. Due to the effect of material removal on the blade’s dynamic properties, spindle speed needs to be adjusted throughout the machining process to keep it within the continuously changing stability gaps. This paper describes in detail an optimization procedure for the design of stock allowance distribution in such a way that a continuous spindle speed modulation is possible that avoids chatter throughout the machining process by maintaining spindle speeds within stability gaps. The presented algorithm uses finite element analysis software to simulate the effects of stock allowance distribution and material removal on workpiece dynamical properties. This information is then coupled with a stability model based on the Jacobian of the cutting force with respect to the regenerative deflection to identify the varying stability gaps throughout the machining process. The proposed method was experimentally verified.
