“…This process planning approach acts as an enabler for flexibly and accurately manufacturing complex parts that are traditionally impossible to produce by either individual CNC machining or additive processes. The production time can be significantly reduced compared to the state of the art methods presented by Jeng and Lin [6] and Karunakaran et al [9], since the redundant face milling operations for each layer have been removed. The total material consumption can also be reduced as a result of being able to generate optimised support structures.…”

“…Jeng and Lin [6] used a laser to melt the mixed powders (Fe, Ni and Cr) and once one cladding operation was accomplished, the surface of the cladding was milled in order to achieve the desired accuracy and maintain a flat surface for the next cladding operation, until the entire mould was produced. Liou et al [7] and Zhang and Liou [8] incorporated a laser cladding unit with a five-axis milling machine, where any deposition feature can be built in the horizontal direction by rotating the workstation.…”

“…Kerbrat et al [24] used a design for manufacturing (DFM) approach to analyse features in the design stage and subsequently identified which features would benefit from being made either by machining or additive process in terms of feature complexity. In the combination of additive and subtractive processes, a typical process planning approach is to face machine the top of each layer after it is deposited [6]. Hu and Lee [25] introduced a concave edge-based part decomposition method, which splits the part into a number of subparts to eliminate undercut edges during machining.…”

As a result, hybrid manufacturing processes -where varied manufacturing operations are carried out -are emerging as a potential evolution for current manufacturing technologies. However, process planning methods capable of effectively utilising manufacturing resources for hybrid processes are currently limited. In this paper, a hybrid process, entitled iAtractive, combining additive, subtractive and inspection processes, along with part specific process planning is proposed. The iAtractive process aims to accurately manufacture complex geometries without being constrained by the capability of individual additive and subtractive processes. This process planning algorithm enables a part to be manufactured taking into consideration, process capabilities, production time and material consumption. This approach is also adapted for the remanufacture of existing parts. Four test parts have been manufactured from zero and existing parts, demonstrating the efficacy of the proposed hybrid process and the process planning algorithm.

“…Finally, the sturdy mold is removed to reveal the final part, which can be machined if necessary. Contrary to the typical design sequence (Jeng & Lin, 2001) constructed their own motion and control system for a Selective Laser Cladding (SLC) system and integrated the milling head, which evens out the deposition surface after every two layers. Clearly, each system has its advantages and contributes differently to the RM industry.…”

Laser cladding technology enables the regeneration or manufacturing of machine parts with the improved surface layer properties. The materials applied during the laser cladding processes very often contain hard and wear-resistant tungsten carbide (WC) particles. However, the parts obtained after the laser cladding have usually unsatisfactory surface quality and thus require post-process finishing. In addition, the content of WC particles causes that clad layers are difficult to cut. Therefore, in order to improve their machinability, the laser-assisted machining (LAM) technology can be applied. Nevertheless, the material removal mechanisms during LAM of WC/NiCr clad layers are not recognized. Thus, this study is focused on the estimation of minimum uncut chip thickness and analysis of cutting forces which are important factors describing the chip decohesion process. The proposed method is based on the novel approach dedicated directly to the oblique cutting, considering the zeroth tangential force increment located onto rounded cutting edge. The experimental procedure involves cutting force component (F c , F f , F p ) measurements in the range of variable cutting conditions, as well as the cutting tool's micro-geometry inspection. On the basis of the measurements carried out, the force regression equations are formulated and subsequently applied to the determination of tangential force expression. Subsequently, the minimum uncut chip thickness is calculated on the basis of the equation derived from the zero tangential force increment condition and presented in function of cutting speed. The obtained results enable the effective selection of the cutting parameters during LAM of WC/NiCr clad layers.
