“…The geometry of the uncut chip and the coupling limits of the tool were defined for orthogonal, tangential and coaxial chip milling. This model shows a good agreement with the experimental data where the error in the force calculations is less than 10% for different cutting parameters and less than 3% in the quality analysis of the machined part [9]. Also, MATLAB programmed correlation software and CAD programming software were developed.…”

In the present study, the incidence of the variation in feed rate per tooth and depth of cut for SAE 4340 alloy steel and SAE J431 steel castings was analysed and in which material this variation is most noticeable. For this purpose, the machining process studied was milling. This is a machining operation in which a workpiece is passed in front of a rotating cylindrical tool with multiple cutting edges. For this study, the feed rate per tooth and depth of cut were varied by 4 values each. The feed rate ranged from 0.002 mm to 0.008 mm and the depth of 2 mm to 8 mm found that for both parameter variations cutting speeds always decrease with increasing both feed per tooth and depth of cut and that feed per tooth and depth of cut significantly affect process costs.

“…Orthogonal turn-milling is an effective method for external machining of the workpiece, especially for miniature parts, which is because of the small axial cutting force. Karagüzel et al [1] have established the geometric, kinetic and mechanical models of orthogonal turn-milling and coaxial turn-milling. Egashira et al [2] developed a turn-milling machine tool for small parts, which can machine microshafts with diameter of 50 lm.…”

Turn-milling is a relatively new cutting process combining the both advantages of turning and milling, during which the tool and the workpiece rotate simultaneously. Due to the small axial cutting force, turn-milling is especially suitable for the machining of miniature parts. Usually, the surface quality is characterized by roughness, but the size of miniature parts is difficult to meet the requirements of the sampling length, which will have a huge influence on the characterization results. This paper introduces the box-counting method for image fractal dimension estimation to evaluate the surface quality of miniature parts during orthogonal turn-milling. The fractal dimension is an independent parameter for scale, which is not influenced by the sampling length. The effect of cutting parameters on surface quality of miniature parts during turnmilling is also studied.

“…Turn-milling technology is an advanced machining method developed in 1980s [1,2].Instead of turning and milling, turn-milling can effectively utilize the existing cutters to process the workpieces of various materials, and realize the machining of various kinds of rotary parts and thin wall parts [3].The utility model has the advantages of high processing efficiency, high machining precision, long tool life, stable cutting, no chip breaking, and can finish the processing which is usually difficult to be realized by a single turning or a milling machine [4][5][6].…”

The mathematical model of machined workpiece by orthogonal turn-milling with ball-end milling cutter is established, which takes the effect of ball-end milling cutter eccentricity into account. The simulation steps and flow chart of the algorithm are also given in this paper. The relation between representative turn-milling parameters (feed per tooth) and machined surface micro-pattern has been ascertained, which provides evaluation mechanisms reference for surface micro-pattern in the turnmilling affected by other machining parameters, the surface micro-pattern simulation is developed base on computer programming. The consistency of surface micro-pattern in simulation and machining experiment is verified, which is in the aspect of shapes and positions layout of peaks and valleys on the micro-pattern. This model is effective and feasible that it also can provide a basis for rational selection of cutting parameters in turn-milling.
