                    Table 4 lists the tool types required for each step, the   processing content of each tool. Due to the vast amount of
                custom names of the tools, and brief information about the   brand information, specific brands are not mentioned.

                8  Process design
                    Table 5 lists the process sequence of each step in the
                combined turning and milling finishing process, along with
                a brief description of each procedure. From the design of
                the entire process route, it can be seen that the combined
                turning and milling process completes 90% of the machining
                content in a single setup, which not only has high machining
                efficiency but also effectively guarantees the accuracy of
                various dimensions and positional shapes. This fully leverages
                the advantages of combined turning and milling, allowing        Figure 6   Installation
                for flexible adjustments to the process and related process
                resources according to actual needs. This article is for reference
                only.
                    Next, we will conduct a simple process breakdown of
                some issues that should be noted during certain procedures in
                processing.
                8.1  OP1 installation
                    As shown in Figure 6, after installing the parts, set the
                position of M842, with G54 set on the right end face of the
                part. Use a Renishaw probe to measure the machining origin of
                                                                            Figure 7  Center frame position
                the part, and set up the coordinate axes on the machine tool.
                8.2  OP3 center frame position                    for the frame position is good. Soft material should be added
                    The position of the center frame should be placed in the   on top of the center frame for protection as shown in Figure 8,
                middle of the shaft as shown in Figure 7. A roughness of Ra1.6   because during rough turning, the iron chips are in block form,
