In order to solve the problem of machining error of noncircular gears, a method based on the analysis and research of the accuracy of noncircular gears based on CNC machining technology under the cloud computing platform is proposed to further improve the technical accuracy of noncircular gears. The error and error items are analyzed mainly, and a model framework based on cloud computing platform is proposed on this basis. The architecture of the system is deeply analyzed, focusing on the dynamic integration method of gear cloud measurement system resources based on cloud platform, building a gear cloud measurement system based on cloud computing platform, and testing needs to use Hadoop to install the software that needs to be prepared: virtual machine version, VMware Workstation-14.0.0 build-6661328, Linux version. The results show that the technical support of the cloud computing platform can effectively improve the accuracy of noncircular gears.

“…It can be known from the research contents of Zhu and Li [ 31 ] that the forming angles on the difficult-forming surface decreases while the forming angles on the easy-forming surface increases when the sheet postures are inclined from the difficult-forming surface to the easy-forming surface, so the thinning degree on the easy-forming surface gradually increases and the thinning degree on the difficult-forming surface gradually decreases.…”

“…Tanaka et al [ 30 ] used the inclined plane to cut the model to generate the toolpath to obtain the inclined sheet and realized the non-rupture forming of the formed part with large forming angles. Zhu and Li [ 31 ] obtained the inclined sheet in different orientations directly by controlling the squeezing movement of the forming tool and realized the non-rupture forming of the sheet metal part, including straight wall. The above-mentioned scholars have proved the feasibility of the sheet tilting method in the CNC incremental forming process through their own research, but the influence of sheet tilting on forming quality was not studied.…”

In the CNC incremental forming process, the sheet tilting method can be used to realize the non-fracture forming of a surface with large forming angles. However, the forming effect of the formed part will have big differences when the inclined angle of the sheet is different. Therefore, four different tilted sheets with inclined angles of 15°, 20°, 25°, and 30° were used to study the influence of sheet tilting on forming quality by using 1060 Aluminum sheet as the forming sheet in single point CNC incremental forming. First, the influence of four different inclined angles of the sheet on the overall thickness distribution, plastic strain, and material flow of the formed part was studied by using numerical simulation. Then, the influence of four different inclined angles of sheets on the profile accuracy and thickness thinning rate of the formed part was studied through single point incremental forming experiments. The research results show that sheet tilting has little effect on the profile accuracy of the formed part, but has a great influence on the material flow, plastic strain, and thickness distribution.

“…For the forming of straight wall parts, in addition to the multi-pass incremental forming strategy, the strategy of sheet metal posture adjustment can also be used, which is to adjust the direction of sheet metal posture so that the forming angle is less than the forming limit angle of sheet metal. Li et al [10] proposed a method to adjust the sheet metal posture in real time in multiple directions. In this method, the sheet metal part with complex shape is decomposed into several regions according to the features, and then different sheet metal posture adjustments are applied to each feature region to generate multi-directional sheet metal posture adjustment toolpaths.…”

In order to realize the CNC incremental forming of the straight wall parts, a CNC incremental forming method with the sheet metal posture adjustment in multiple directions based on the model partition and the non-steep surface was proposed in this paper. With the help of the non-steep surface, the sheet metal posture is adjusted to reduce the forming angle of the straight wall; to ensure the straight wall to be formed without breaking. The results of numerical simulation shows that the method proposed in this paper can form the straight wall parts that cannot be formed by the traditional multi-pass incremental forming, and the straight wall parts of the formed parts have better contour accuracy, uniform thickness distribution and applicability.
