Simulation of manufacturing strategy of an orthotic boots shoe insole product with a Computer-Aided Manufacturing for club foot patient

Abstract

In this paper, the design of orthotic boots in the club foot patient is investigated concerning the optimum condition of cutting parameters using computer-aided manufacturing. 3D CAD model insole is obtained from the scanning process until the design phase using reverse innovative design method. 3D CAD Model insole is designed using curve Base Modeling. From this design, simulated optimization can be obtained from Computer-Aided Manufacturing (CAM). Optimal manufacturing time optimization is simulated on the CNC Milling machine with the Taguchi approach. Six selected parameters containing toolpath machining, feed rate, spindle speed, depth of cut, Cutter selection, and insole dimension size are of particular interest. It is found that the design layout L2736 gives the most optimal simulation manufacturing using toolpath strategy tep and shallow finishing with spindle speed 1500 rpm, STEPD down 3 mm, Step over 2 mm, and 2mm Cutter diameter, on the model tolerance size 0.75 mm.

Optimization of virtual design and machining time of the mold master ceramic jewelry products with Indonesian batik motifs

“…Before the NC code is executed, the CAM program that has been created can be monitored by running a virtual simulation process to see the complete feed of the overall surface geometry and the amount of time it takes to complete the machining process. This has also been proven and successfully carried out by previous researchers (Chang, 2015b;Chang, 2015c;Oancea, 2013;Mircheski et al, 2019;Vardhan and Sridhar Babu, 2020;Fergiawan et al, 2021;Anggoro et al, 2021;Anggoro et al, 2022). In PowerMill, there is a choice of machining process strategies from 3 axes to 5 axes, but in this case, it adjusts to the availability of CNC machines that only work on three axes.…”

“…The results of all virtual machining processes from both ceramic models of pendant jewelry with the Indonesian Batik Combination pattern have also been proven effective and successfully carried out by previous researchers on CNC machines [Clayton, 1986;McLaughlin, 1988b;Oancea, 2013;Chang, 2015c;Vardhan and Sridhar Babu, 2020;Ratnanta et al, 2020;Fergiawan et al, 2021;Anggoro et al, 2021;Anggoro, et al, 2022;Bawono et al, 2019;Yuniarto et al, 2022] with maximum results and Naruna has traded some. This research discusses the virtual machining stage in the Power Mill CAM software because the NC Code results can be directly executed on a CNC router machine that uses a Mach3 post processor or is compatible with Power MILL.…”

“…3.3.1 Setting the placement of the 3D CAD ceramic model for Indonesian batik jewelry 3D models of five ceramic pendants with motifs of Batik Indonesia Combination according to a design that the Engineer Team has mutually agreed upon and Naruna are placed simultaneously and aligned in two rows of square blocks according to the position of the CNC router machine table (Figure 12). Furthermore, these two models were set up for model placement through virtual design and machining using CAD and CAM software as has been done by previous researchers (Clayton, 1986;Homer and Skaar, 1991;Yao, 2017;Zhang et al, 2018;Fergiawan et al, 2019;Fergiawan et al, 2021;Anggoro et al, 2022). The material block sizes prepared in CAD are 183 × 120 × 11 mm and 350 × 220 × 11.68 mm (see Figure 12B).…”

“…These results can be realized well if the NC Code output we produce in this paper can run on a CNC router machine according to the machining parameters set in Table 1. Previous researchers have also used this parameter well (Ullman, D. G., 1992;Yao, 2017;Zhang et al, 2018;Fergiawan et al, 2021;Yuniarto et al, 2022). The final result of the machining process for both types of pendant jewelry designs (Figure 5) can be presented in Figure 13 and manufactured using a CNC router machine.…”

Product Design Trends within the Footwear Industry: A Review

“…They proposed a lattice structure that can adjust the diameter of struts inside the sole, with future research planned to explore additional factors for further optimization. Fergiawan et al [110] studied the design of orthotic footwear for individuals with specific foot shapes, using scans of the sole to obtain correct geometry for the inner sole. Simulation models were employed to achieve optimal design parameters and reduce shoe manufacturing time, utilizing CAM (Computer-Aided Manufacturing) and CNC (Computerized Numerical Control) machine techniques along with Taguchi methods.…”
