Machining with five-axis equipment can offer manufactures many advantages, including dramatically reduced setup times, lower costs per part, more accurate machining and improved part quality. While in five-axis machining, the tool axis changes frequently, even the most experienced engineers are difficult to judge the correctness of its tool path. So in this paper, taking five-axis machine tools as the prototype, the process of building NC simulation platform was introduced by using simulation software VERICUT. After that, it introduced simulation operations, verifying the simulation platform and data simulation function. Finally, the correctness of the simulation was verified by machining experiments. Researching CNC machining process on the VERICUT platform, the research results were used in five-axis machining simulation of integrated impeller and it improved both the process capacity and efficiency of the integrated impeller greatly. This method obtained in this paper could eliminate the colliding and interference phenomenon during test cut, reduce costs, improve the efficiency of programming and shorten the manufacturing period.

In view of the spiral bevel gear machined by the semi-generating means, a new method to create 3D solid model is proposed. The equation of tooth profile surface is deduced from the principles of spiral bevel gear engagement and cutting, according to the position relationship of the machine tool, the cutting tool and the workpiece, along with the cutting tooth process. Then the three-dimensional solid model of spiral bevel gear is developed with the delphi program using the known parameters and the above mathematic equations. The effectiveness of this method has been demonstrated.

In this paper, based on the octree partition, bounding boxes and triangulated surface model, we developed a new virtual material removal method for machining of 3D complex surfaces. In this method a new tri-prism space partition algorithm based on octree and triangulated surface model is applied to partition the 3D complex surfaces. Traditional triangular-faced algorithm is used in 3-axis machining simulation, which is computationally expensive and memory demanding. In contrast, this paper presents a virtual material removal model using the dynamic tri-prism space decomposition algorithm (i) to represent 3D complex objects, (ii) to reduce the computation complexity, and (iii) to accelerate the model updating procedures in a graphic simulation process. Based on mathematical model of virtual material removal, the 3D model of virtual CNC machining process was developed.

This paper presents the development of a simulation program to improve the process planning and simulation for 4th axis machining in NX CAM systems. A customised graphical user interface (GUI) was developed to enhance the simulation process planning and reduce the dependency on the user’s experience while developing the machining program in NX CAM systems. The simulation operation was recorded using a journaling tool available in NX CAM while visual basic programming was utilised to customise the code. The results indicate that the developed programs are capable of optimising the 4th axis machining simulation by reducing the processing steps and time with minimum process planning tasks.

Performance Results

GPUs (Graphics Processing Units), traditionally used for 3D graphics calculations, have recently got an ability to perform general purpose calculations with a GPGPU (General Purpose GPU) technology. Moreover, GPUs can be much faster than CPUs (Central Processing Units) by performing hundreds or even thousands commands concurrently. This parallel processing allows the GPU achieving the extremely high performance but also requires using only highly parallel algorithms which can provide enough commands on each clock cycle. This work formulates a methodology for selection of a right geometry representation and a data structure suitable for parallel processing on GPU. Then the methodology is used for designing the 3-axis CNC milling simulation algorithm accelerated with the GPGPU technology. The developed algorithm is validated by performing an experimental machining simulation and evaluation of the performance results. The experimental simulation shows an importance of an optimization process and usage of algorithms that provide enough work to GPU. The used test configuration also demonstrates almost an order of magnitude difference between CPU and GPU performance results.
