“…By comparing Sa and Rt values, it found that vertical upward is the optimal cutting path [25]. Chen et al [26] studied the effect of different angle combinations on the surface topography in multiaxis milling. Better surface roughness could be achieved when rotation angles are 0 (positive lead), 60 (combination of positive tilt and positive lead), 90 (positive tilt), and 330 (combination of negative tilt and positive lead).…”

It has been proved that surface integrity alteration induced by machining process has a profound influence on the performance of a component. As a widely used processing technology, milling technology can process parts of different quality grades according to the processing conditions. The different cutting conditions will directly affect the surface state of the machined parts (surface texture, surface morphology, surface residual stress, etc.) and affect the final performance of the workpiece. Therefore, it is of great significance to reveal the mapping relationship between working conditions, surface integrity, and parts performance in milling process for the rational selection of cutting conditions. The effects of cutting parameters such as cutting speed, feed speed, cutting depth, and tool wear on the machined surface integrity during milling are emphatically reviewed. At the same time, the relationship between the machined surface integrity and the performance of parts is also revealed. Furthermore, problems that exist in the study of surface integrity and workpiece performance in milling process are pointed out and we also suggest that more research should be conducted in this area in future.

“…In another analogous approach, free-form tool paths were favoured with respect to machining time in three-axis mode, but parallel tool paths were found to offer better quality and accuracy in two-axis mode for complex free-form surfaces. 10 Influence of tool inclination angles (tilt and lead) with respect to the feed direction on surface roughness, micro-hardness and residual stress state was studied experimentally in Chen et al 11…”

Computer-aided manufacturing systems are considered as ‘what-if’ processors, whereby the user suggests manufacturing features and for each one of them a tool and a machining strategy, whereas the system computes tool paths and generates a computer numerical control program. Given the multitude of factors for which decisions are needed, complexity is high. In addition, given the executive nature of computer-aided manufacturing systems, the user relies on experience in exploring parameter value combinations in order to obtain good results. In this work, structured generation of a representative subset of the parameter combination space is advocated using the Taguchi approach. This is applied to parts that are simpler than the average part, since they consist of a single, repeating, yet geometrically complex, machining feature involving sculptured surfaces, such as helical bevel gears. The lack of multiple features reduces the solution space, enabling a manageable number of experiment runs from which good results for roughing and finishing are attained. Statistical processing of these results also point to relative significance of machining strategy parameters within the particular space explored and for the particular weighted criteria employed, that is, rest material, machining time and gouge volume. Excellent results are obtained in this way, based on the machining simulation capabilities of modern computer-aided manufacturing systems and bypassing the inherent lack of intelligence of the latter.

Surface integrity determines the performance and quality of the end product. It often needs to change the input parameters, such as cutting parameter, cutting tool geometry and material, and tool coating, to obtain the best machining surface integrity. This article presents and demonstrates the effectiveness for the multi-objective optimization of cutter geometric parameters for surface integrity of milling Ti-5Al-5Mo-5V-1Cr-1Fe titanium alloy via grey relational analysis coupled with the Taguchi method, entropy weight method, and analytic hierarchy process. The main influence factors are chosen as radial rake angle, primary radial relief angle, and helix angle, while surface roughness and residual stress are taken as performance characteristics. Based on the Taguchi method, an L16 (43) orthogonal array is chosen for the experiments. The effect of cutter geometric parameters on surface roughness and residual stress is analysed by signal-to-noise ratio. Then, the multiple objectives optimization problem is successfully converted to a single-objective optimization of grey relational grade with the grey relational analysis. The weight coefficient for grey relational grade is determined by entropy weight method integrated with analytic hierarchy process. The results show that the order of importance for controllable factor to the milling surface integrity, in sequence, is radial rake angle, primary radial relief angle, and helix angle. The validation experiment verifies that the proposed optimization method has the ability to find out the optimal geometric parameters in terms of milling surface integrity.
