Design and Manufacturing of Customized Braces for Scoliosis Treatment

A new method to design and manufacture customized braces is introduced in this research for scoliosis treatment. In this method, a geometric model of a scoliosis patient’s torso is achieved using a laser optical scanning device. The brace geometry is obtained by generating the offset geometry of the torso’s surface, selecting vertical boundaries, removing holes and noise data, creating symmetrical geometry, and modifying the geometry near the pelvis curves. Manufacturing of the brace is conducted by producing a male die with a sculptured surface using a custom-designed 5-axis CNC milling machine and creating the plastic brace using a thermoforming process.

Design And Manufacture

In order to optimize the CNC milling machine structure, the system modeling, simulation, and virtual prototyping technology are used in this paper. It has built 3D virtual prototype model and finite element model of the upright post on Pro/E, ADAMS and ANSYS platforms respectively. The modal analysis of different rib column has been done. The top twenty frequencies and mode of those upright posts are calculated by ANSYS software. Through the modal analysis and compared with different column structure, the optimization column geometry is determined, and the main spindle speed should not be greater than 9000 r/min. These will provide important references for the general design and manufacture of the CNC milling machine.

This research proposes a new application of 3-axis CNC milling machine for polishing the 60 HRC hardness steels. The rotary polishing tools are designed by refer to the end-mill ball nose’s design. The diamond powder are coated in rotary polishing tools by resinoid bonding method and concentrated in 4.4 karat/cm2. The Zig-milling tool paths are used to polish the hardness steel. After polishing, the confocal laser scanning microscope is used to analyze the arithmetic mean surface roughness of the hardness steels. The L12 orthogonal array of the Taguchi’s method is selected to conduct the matrix experiment to determine the optimal polishing process parameters. The diamond grit size and cutting speed of the rotary polishing tools, feed rate and step over of the tool path, the depth of polishing process penetration, and polishing time are used to study. The combination of the optimal level for each factor of the hardness steel polishing process are used to study again in the confirmation experiment. The predicted signal to noise ratio of smaller - the better under optimal condition are calculated by using the data from the experiment. The combination of the optimal level for each factor are used to study again in the confirmation experiment and the result show that polishing time was a dominant parameter for the surface roughness and the next was depth of penetration. The response surface design is then used to build the relationship between the input parameters and output responses. The experimental results show that the integrated approach does indeed find the optimal parameters that result in very good output responses in the rotary polishing tools polished hardness mould steel using CNC milling machine. The mean surface roughness of hardness steel polishing process is improved by the diamond rotary tools with the 3-axis CNC milling machine.
