“…Wang et al [7,8] developed the curvature catering method to position the disk cutter by making the enveloping surface of the tool and the design surface having the same derivatives up to the third order in the normal section perpendicular to the feed direction. The gouge checking and tool path generation for the curvature catering method were resolved by Li et al [9,10]. Chiou [11] presented a tool positioning algorithm by swept envelope approach for 5-axis ruled surface machining.…”

In this paper, a new 5-axis tool positioning algorithm called the rotary contact method (RCM) for open concave surface machining using the toroidal cutter is developed. The RCM comes from the reverse thinking of multipoint machining (MPM) method and apparently distinguishes the traditional tool positioning principles, as it determines the optimal tool positions based on the offset surface instead of the design surface. The basic idea of the RCM is to determine the initial tool location first and then rotate the tool for required contact. The RCM can not only guarantee gouge fi-ee tool positions without the additional local gouge checking and correction process but also effectively produce big machined strip width for open form suiface machining just like the MPM. Besides, this new method is simple to implement. Machining simulation was performed to verify the validity of the RCM.

“…The faster machining times and superior surface finishes characteristic of 5-axis machining are achieved by using flat and rounded endmills instead of a ball endmill [1][2][3][4][5]. In addition, the complex multiple setups necessary in conventional 3-axis machining can be done more efficiently with a single setup [6].…”

In this paper, the 5-axis tool path that has been generated on the cutter contact (CC) surface is generated on the cutter location (CL) surface, and the CL surface deformation approach that inversely deforms the 3-axis tool path generated on the deformed CL surface to a 5-axis tool path is introduced. The CL point computation and interference check based on the CL surface is faster and more robust than that based on the CC surface. The proposed CL surface deformation approach can be used if the orientation of the cutter is predefined. By the CL surface deformation approach, the 5-axis tool path generation time can be reduced to that of a 3-axis, since the complexity of a CL surface deformation is linear and because the 3-axis tool path generation and gouge removal algorithms are used at the deformed CL surface.

“…A lot of research has been done on this subject ( [2], [3], ... , [12]), but the results have not been implemented in commercial CAD/CAM-systems. Another important contribution to the improved machining was the replacement of the ballnose-cutter with a barrel-cutter for the machining of the fillet.…”

Abstract:This paper discusses experiences from a research project aiming at the improvement of the machining process for Hydro Power Plant Turbines. Both technical results and experiences from the process to achieve these results are expressed. A number of improvement features regarding 5-axis machining of sculptured surfaces are discussed. Major findings are pointed out as the lack of suitable functions in the CAD/CAM system to cope with the challenges of this· specialised product. Improved machining strategies as "Parallel Cut", "Constant Gap Strategy", and "Multi-axis Plunge Cutting" are introduced. The outcome of the project was a new method for manufacturing of turbines. Based on the experience in the development project, reflections regarding organisational mechanisms for Quantum Leap Improvement are discussed.
