Abstract In orthopedic surgery, bone cutting is an indispensable procedure followed by the surgeons to treat the fractured and fragmented bones. Because of the unsuitable parameter values used in the cutting processes, micro crack, fragmentation, and thermal osteonecrosis of bone are observed. Therefore, prediction of suitable cutting force is essential to subtract the bone without any adverse effect. In this study, the Cowper-Symonds model for bovine bone was developed for the first time. Then the developed model was coupled with the finite element analysis to predict the cutting force. To determine the model constants, tensile tests with different strain rates (10−5/s, 10−4/s, 10−3/s, and 1/s) were conducted on the cortical bone specimens. The developed material model was implemented in the bone cutting simulation and validated with the experiments.

Data Processing Methods

In this paper, the turning process of 45# steel was simulated and analyzed based on the metal cutting finite element analysis software DEFORM-3D. The analysis result of cutting force was gained. However, due to some reasons of the software itself, there is noise data in analysis results. Thus, it’s needed to filter the data to extract useful information. The selected short-duration and steady-state cutting force data was processed with the use of six-sigma rule through mathematical statistics analysis. As a result, some bad data were rejected. Noise data was filtered out via wavelet analysis and the processed function curve of cutting force that changes with time during the whole cutting course was gained.

This paper reports two investigations on the edge chipping in rotary ultrasonic machining using finite element analysis (FEA). The first FEA investigation establishes a relationship between edge chipping thickness and cutting force. The second FEA investigation is to understand the effects of three parameters (cutting depth, support length, and pre-tightening load) on edge chipping thickness. The investigation results showed that the edge chipping thickness could be reduced by increasing support length and decreasing cutting force.

Abstract This paper presents analysis of flank wear influence on forces in orthogonal turning of 42CrMo4 steel and evaluates capacity of finite element model to provide such force values. Data about magnitude of feed and cutting force were obtained from measurements with force tensiometer in experimental test as well as from finite element analysis of chip formation process in ABAQUS/Explicit software. For studies an insert with complex rake face was selected and flank wear was simulated by grinding operation on its flank face. The aim of grinding inset surface was to obtain even flat wear along cutting edge, which after the measurement could be modeled with CAD program and applied in FE analysis for selected range of wear width. By comparing both sets of force values as function of flank wear in given cutting conditions FEA model was validated and it was established that it can be applied to analyze other physical aspects of machining. Force analysis found that progression of wear causes increase in cutting force magnitude and steep boost to feed force magnitude. Analysis of Fc/Ff force ratio revealed that flank wear has significant impact on resultant force in orthogonal cutting and magnitude of this force components in cutting and feed direction. Surge in force values can result in transfer of substantial loads to machine-tool interface.

Polycrystalline diamond (PCD), is a tool material and widely used in nonferrous metal processing due to its excellent properties, such as high hardness, high wear resistance, high thermal conductivity and low friction coefficient. Considering the friction between the cutter and the workpiece, the heat generated by the elastic-plastic deformation and the heat transfer between the cutter and the workpiece. The finite element analysis software ABAQUS was used to study the effect of different processing parameters on the temperature field distribution and cutting force of the cutter, in the case of welded PCD double-edge end milling copper. The temperature distribution of cutting tools and the changing trend of cutting force with milling parameters was obtained. These technological parameters include the milling rotation speed n, the axial milling depth ap, and the feed rate f. The simulation results show that the tool temperature increases with the increase of milling depth, feed per revolution and rotation speed. However, the tool temperature has little effect on the tool life. Under the condition of satisfying the work-piece surface quality and machining efficiency, low speed, small milling depth and small feed should be selected as far as possible. Milling depth has a great influence on cutting force. When milling speed is about 2400 r/min, the axial milling depth is 0.3 mm, and the feed is 0.2 mm/r, which can obtain small milling force and lower tool temperature, and further extend the life of PCD tool.

Fir tree groove broaching rebound has an obvious impact on the wheel groove manufacturing accuracy. The prediction of wheel groove rebound in the broaching process is an important aspect to improve the manufacturing precision of wheel groove. The deformation caused by cutting force is the main factor that decides wheel groove broaching deformation. For the problem of tree wheel groove broaching deformation and rebound: Firstly, calculating the actual cutting force through experiment and empirical formula of cutting unit cutting force, and then loading the cutting force as the initial load in the wheel groove line; Secondly, using the finite element software-Abaqus to copy the analysis of the wheel groove in the broaching process; Finally, comparing the rebound deformation curve and the data generated by the simulation with the actual ones measured by the worked wheel groove, and the result of simulation is consistent with the rebound. The prediction of wheel groove broaching rebound provides the basic theory to improve the wheel groove broaching of rebound problem.
