“…While additive manufacturing (AM) has demonstrated its potential to be a disruptive technology it still suffers from many drawbacks with regard to the creation of functional part surfaces, low dimensional accuracy, and defects from the deposition process. To counter these disadvantages, modern subtractive manufacturing (SM) machine tools are incorporating AM technology to create hybrid machine tools [1]. These machine tools have the ability to deposit material and remove material to manufacture a part with the production speed and material efficiency of AM and the dimensional accuracy of SM.…”

Hybrid manufacturing machine tools have great potential to revolutionize manufacturing by combining both additive manufacturing (AM) and subtractive manufacturing (SM) processes on the same machine tool. A prominent issue that can occur when going from AM to SM is that the SM process toolpath does not account for geometric discrepancies caused by the previous AM step, which leads to increased production times and tool wear, particularly when wire-based directed energy deposition (DED) is used as the AM process. This work discusses a methodology for approximating a part’s surface topology using on-machine contact probing and formulating an optimized SM toolpath using the surface topology approximation. Three different geometric surface approximations were used: triangular, trapezoidal, and a hybrid of both. SM toolpaths were created using each geometric approximation and assessed according to three objectives: reducing total machining time, reducing surface roughness, and reducing cutting force. Different prioritization scenarios of the optimization goals were also investigated. The optimal surface approximation that yielded the most improvement in the optimization was determined to be the hybrid surface topology approximation. Furthermore, it was shown that when the machining time or cutting force optimization goals were prioritized, there was little improvement in the other optimization goals.

Currently, in manufacturing industries, hybrid manufacturing (HM) has emerged as a paradigm shift since it provides numerous benefits which include lead time reduction, cost savings and waste minimization. Hybrid additive manufacturing (HAM), being one of the tiers of HM, couples additive technology with traditional or non-conventional technologies resulting in the enhancement of product performance. For efficient part fabrication considering technical, economic, and environmental benefits, process planning is vital. The literature review reveals that due to the unexplored potential of additive manufacturing (AM) technologies and lack of knowledge of complexities in HAM, the process planning in HAM is still in its infancy. By providing a systematic literature review of different techniques of process planning, this paper tries to bridge this research gap in HAM. Furthermore, the challenges and opportunities in process planning of HAM are also discussed which will help to exploit the future horizons in this field. Ninety-six journal research articles were considered in the systematic literature review (SLR) study which uncovered eight categories of process planning and fifteen challenges and opportunities for future trends. It is concluded that a large research gap in the process planning of HAM needs to be fulfilled to secure time and enhance quality and functionality in the advanced manufacturing era.
