“…Classification of composites can be made as follow [ [6] During machining of fibre-matrix composites unfavourable phenomena occurs, which lead to destruction of the work piece or inability to the proper quality obtainment of free surface after the machining process [1,2,4,6,7]. Parts used for female mould matrix with free surfaces are manufactured by pressing of composite (Fig.2) or machining process [2,3,5,6].…”

Paper presents some aspects of fibre composite milling. Composites are particularly applied in the sectors such as aircraft, aerospace and automotive industries for they are light and relatively easy can be forming in the desired shapes. The purpose of research was optimization of free form milling considering the machined surface quality (mainly roughness). After proper cutting parameters selection (feed and cutting speed) the example parts with free form surface were machined.

“…So the dynamics of the flycutting must be analysed (Cheung et al, 2008b). According to the symmetrical characteristic of the V-shaped cutting tool, the cutting force along the flycutting spindle direction between the V-shaped tool and workpiece is counteracted.…”

Ultra-precision diamond flycutting is an important method to manufacture micro V-groove with sub-micrometer form accuracy. The relative vibration between the tool and the work piece is one of the most critical factors which determine the manufacturing precision during the flycutting process. In order to restrain the vibration influence, a vibration analysing method in flycutting process is presented. The dynamical model of micro V-groove is established according to the character of ultra-precision diamond flycutting. Three-dimensional topography is simulated with and without vibration. The V-groove surface roughness is analysed based on the spatial frequency spectrum. Ultra-precision flycutting experiments are carried out, and the V-groove surface roughness is measured by the stylus profilometer along the V-groove. The vibration is identified on the basis of spectrum analysis results. The vibration character of flycutting system is obtained, and the cutting parameters are optimised. ) 'Topography simulation and vibration analysis of ultra-precision diamond flycutting micro V-groove', Int.

“…The factors affecting surface generation in UPRM are much more complex as compared with SPDT and conventional milling. Cheng et al (2008) have reported that the factors affecting surface roughness in UPRM include cutting parameters, feed direction, step distance, and tool geometry (swing distance, tool nose radius) while ignored the influence of the workpiece material on surface roughness. Only few studies are found to study the effect of workpiece on the surface generation in ultra-precision milling.…”

Ultra-precision raster milling (UPRM) rotates a single crystal diamond tool to discontinuously remove materials from the workpiece and can directly produce freeform surfaces with sub-micrometric form accuracy and nanometric surface finishing. This paper presents theoretical and experimental investigations on the workpiece material effect on single cutting profile in UPRM. Experiments are conducted to study the material effect on cutting profile by single cutting four materials including copper, aluminium alloy 6061, brass and aluminium bronze under the same cutting conditions in UPRM. A characterisation method is presented in the paper to study the effect of different workpiece material on the cutting profiles in UPRM. The experimental results
