AB - In this study, a quasistatic force-deflection interaction model considering cutting and elastic force was proposed to analyze and compensate for the quasistatic deflection of slender ball-end milling cutter. The theoretical waveforms and peaks of cutting force considering the force-deflection interactions were consistent with the experimental results. The deflection of slender ball-end milling cutter significantly reduces the cutting force, and the Pearson's correlation coefficient between the difference in the peak cutting force and maximum deflection in radial is larger than that of in feed directions. An analysis of the machining error of a cylindrical surface revealed that the deflection of slender ball-end milling cutter had a considerable effect on the machining error, and the compensation of slender cutter deflection effectively reduced the amplitude and fluctuation of the machining error. This work can provide a useful guidance for machining error control in the ball-end milling process of mold surfaces with deep cavities.

AB - Cyber physical system (CPS) requires modeling and virtual simulation of machining processes. Among the many physical quantities simulated by CPS, the cutting force is one of the most important quantities to be simulated. Until now, two fundamental challenges in achieving a functional and virtual machining process simulation system remain-the identification of cutter workpiece engagement (CWE) along a tool path and the development of computationally efficient simulation algorithms. The major bottleneck is the prerequisite requirement to calculate the complex CWE area before calculating the instantaneous cutting force. In this research, we propose an innovative solution to this problem. Using graphics processing unit's (GPU) parallel computing on the direct computation of the instantaneous cutting force (without calculating CWE), the cutting force computation, together with NC simulation, can reach up to 48 fps on a local PC, reaching the goal of CPS and digital twin simulation requirements in real time.

For fast and reliable simulation with 3 axis milling machines, macroscopic approach is often used. The tool is divided in slices around its axis and a mechanistic model is used to predict the elementary cutting forces. In robotic machining, the tool can experience more complex toolpath and its axis may be tilted during machining due to the flexibility of the robot. The paper presents an improvement of the cutting forces model allowing the simulation for cases where the degrees of freedom in rotation of the axis are freed. (C) 2019 The Authors.

For this purpose, machine simulations are used to allow a preliminary characterization of the given process, thus minimizing the number of physical prototypes and scrap parts. However, these simulations are either extremely specialized for single problems, e.g., dynamic machine behavior, or they are simplified to a kinematic simulation of the machine without considering the machine behavior at all. This article presents a new approach for a real-time machine simulation by combining four types of simulations to close this gap. This proposed approach uses a voxel-based material removal inside a kinematic machine simulation as input parameters for a cutting force calculation. Afterwards, the forces are applied to a multi-body simulation of the static machine behavior. Starting point of the simulation is a hardware-in-the-loop coupling of a real CNC and a real-time visualization of a virtual machine tool. The simulation is experimental verified by comparing the simulated cutting forces and displacements with the measured forces during the process and the resulting shape of the manufactured work piece. The presented conclusions show the general applicability of the proposed method for the simulation of milling processes.

It is proposed to save a BSP tree in each dexel to ensure the exact edge determination. Thus, it is possible to combine the advantages of these methods while eliminating their inherent drawbacks. We managed to combine in a single model the dexel models simplicity and efficiency of the Boolean operations implementation with precision modeling of polyhedral surfaces which is the inherent property of BSP-trees. The proposed approach has greatly improved the quality of geometric models of the parts obtained by CNC machining simulation without increasing the time spent on such construction. The experiments were carried out to determine suitable values of the parameters and to confirm the advantages of the proposed approach.

To estimate the amount of machining errors on the machined surfaces, the shape of the machined part should be derived. In computer simulation, a shape of a machined part is derived as a difference set between a workpiece and tool swept volumes. Hence, in this study, the generating method for tool swept volumes under effects of machine tool error characteristics has been proposed based on the tangency condition. In the previously proposed method, it was assumed that there was only one swept state, that is, two curves on a tool that generate tool swept volumes. However, there are other swept states of a tool, for example, two lines and a circle that generate tool swept volumes, and tool swept volumes of such states cannot be derived by the previously proposed method. Hence, in this paper, swept states of the generalized tool are classified as tool swept types based on the analysis of the tangency condition. Furthermore, the generating method of tool swept volumes for each tool swept type is proposed.
