“…In manufacturing, the advent of computer numerical control (CNC) machining creates a form of ubiquitous computing, and provides an effective simulation as it becomes a necessity. CNC simulations have been developed in virtual environments for numerically controlled (NC) tool path verification and machining process optimisation 2 . However, limitations still exist even though virtual reality (VR)-based systems have already been applied broadly in the manufacturing industry.…”

This study presents a modular-based implementation of augmented reality to provide an immersive experience in learning or teaching the planning phase, control system, and machining parameters of a fully automated work cell. The architecture of the system consists of three code modules that can operate independently or combined to create a complete system that is able to guide engineers from the layout planning phase to the prototyping of the final product. The layout planning module determines the best possible arrangement in a layout for the placement of various machines, in this case a conveyor belt for transportation, a robot arm for pick-and-place operations, and a computer numerical control milling machine to generate the final prototype. The robotic arm module simulates the pick-and-place operation offline from the conveyor belt to a computer numerical control (CNC) machine utilising collision detection and inverse kinematics. Finally, the CNC module performs virtual machining based on the Uniform Space Decomposition method and axis aligned bounding box collision detection. The conducted case study revealed that given the situation, a semi-circle shaped arrangement is desirable, whereas the pick-and-place system and the final generated G-code produced the highest deviation of 3.83 mm and 5.8 mm respectively.

“…However, most of these simulations are problem specific or insufficient for obtaining a working virtual prototype close to the real process. This paper presents the first steps to improve the simulation described in [24] towards a higher degree of realism regarding the kinematics.…”

Machining processes must be adjusted regarding tolerances in dimension and shape to fulfill product requirements. 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.

“…These changes need to be undone after the simulation, respectively before the real production process. For this reason we created a hardware in the loop simulation system that runs in realtime, is easy to establish, detects all problems appearing at the CNC, and simulates material removal in real-time [8].…”

“…Most CNC machines use Windows-based operating systems for their human-machine interface and all required values are visualized within the human-machine interface of the CNC. A program was developed which enables the direct read-out of all the values the machine simulator needs via the human-machine interface by using the Windows DDE service [8]. The great advantage of this solution is that no changes of the hardware configuration of the CNC are required.…”

This paper describes a simulation method for NC programs. The simulation uses real axis values from a real CNC as a basis for the simulation of the generated NC program, respectively the milling strategy. To simulate the milling process by means of material removal at the virtual work piece a real CAD core was used. The CAD kernel based material removal simulation allows a close to reality simulation of the real executed NC program and enables a comparison between the simulated work piece geometry and the target CAD geometry directly in a CAD program.
