??? ??? ?? ????? ????? ????? ???? ?? ??? ?????? ????? ?? ????? ?? ?? ?? ????? ????? ???? ?????, ????? ????? ????? ???? ????? ??? ???????? ?????? ?? ????? ???? ?? ????? ??. Insertion milling (Z-axis milling) is a good example of machining. ?? ?? ??? ?? ?? X ??? ?? Y ??? ?? ??? ??? ????? ????? ?? ??? ????? ????? ?? ???? ?? ??? ?? ?? ????? ?? ???? ????? ???? ???? ??? ????? ?????? ?? ??? ??? ?? ????? ???. Especially in long overhang machining (such as milling deep mold cavities), the traditional flat milling method (i.e. milling from one side of the workpiece to the other) has to reduce the cutting speed in order to minimize the lateral force that can cause chatter. ?????? ??? ??????? ?? ????? ?????? ??? ??????? ?? ????? ????? ?? ???? ????? ??? ?? ??????? ???? ??? ?? ??? ???? ?????? ?????? ?? ????? ???? ????? ????? ?? ???? ????? ??? ??.

He said, "During insertion milling, there is not much heat entering the workpiece because the cutting tool rotates at a fast speed to cut in and out the workpiece. Only a small portion of the workpiece with a moving step makes contact with the tool." This feature is particularly advantageous when cutting difficult to machine materials such as stainless steel, high-temperature alloys, and titanium alloys. ????????? ???? ???? ???? ??? ?????? ????? ??? ????? ?? ??? ???

"??? ???? ?? ????? ??" "?????? ?????? ??? ????? ???? ?? ???? ?? ???? ??? ??? ?????? ??? ?? ?????? ?? ????. Gary Meyers, milling product manager at Seco Tool Company, stated that "the most commonly used areas of insert milling technology are mold manufacturing and aviation industry, as the types of parts in these industries are very suitable for insert milling." Mold manufacturers need to mill various complex shapes on the overall workpiece to form mold cavities, and many aviation parts are also processed from whole blanks. He said, "The cutting amount of these workpieces is astonishing, and in some cases, it is necessary to cut 50% -60% or even more of the workpiece material from the blank." Kenyon Whetsell, Product Manager of DP Technology, the developer of ESPRIT CAM software, pointed out that in addition to manufacturers of complex parts, general-purpose machining workshops can also benefit from the application of insert milling technology. ???? ?? ???? ???? ???? ??? ?????? ???? ?? ??? ?? ?? ???? ??? ????? ?? ??? ?? ??? ?????? ???? 2.5 ??? ??? ??????? ?? ??????? ?? ??? ??? ?? ???? ?? ???? ?? ??? ??????? ?? ??? ??? ??? ?? ?? ?? ?? ?? ?? ?? ?? ?? ??? ???? ??? ?? ?? ???? ????? ??? ?? ??? ?? ????? ????? ?????? ???? ?? ???????? ?? 2.5 ??? ??? ?????? ?? ??????? ?? ???? ???????? ?? ????

The design characteristics of milling cutters: Tool manufacturers have developed various milling cutters that can fully leverage the advantages of milling technology. ?????? ????? ?? ???? ???? ??? ?? ???? ????? ?? ????? ?? ???? ????? ????? ?? ??? ?? ??? ?????? ???? ??. ????? ?????? ???? ?? ????????? ??? 90 ?????? ???? ?? ????? ??? ?? ??? The difference lies in the deviation of the leading angle of the milling blade from the vertical plane by a few degrees, which may be 87 instead of 90. ??? ??? 90° ?????? ???? ?? ???? ????? ??? ???? ???? ??? ????? ?? ??? ??????? ??? ???? ?? ?? ?? ?? ???? ????? ?? ????? ????? ???? ????? ?? ?????? ??? ????? ????? ??. ??? ????? ?? ????? ????? 87 ?? ?? ????? ?? ????? ??? ???? ?? ????? ????? ?? ?????? ??? ????? ??. ?????? ???? ?? ???? ?? ????? ?? ??? ??????? ???? ????? ?? ???? ?? ????? ?? ??? ?? ???? ?????? ???? ?? ???? ?? ????? ?? ??????? ?? ?? ?? ????? ???? ??? ??? ???? ?? ????

For the slot milling cutter used for profile milling, the cutting diameter of the blade exceeds the diameter of the tool body. ???? ?? ???? ???? ???? ??? ?????? ???? ?? ??? ?? ?? ???? ??? ?? ?? ????

He suggested that in order to achieve better machining surface smoothness, the radial cutting step should be reduced, which is the same as the reduced step machining method used in 3D precision milling with ball end mills. ????? ?? ?? ??? ?? ???? ?? ??? ?? ?????? ??? ??? ????? ?? ??? ????? ????? ?? ????? ?? ??? ????? ?? ????? ?? ???? ???? ???? ?? ????? ???? ?? ???? ??. ????? ?? ????? ?? ??? ??????? ?? ??????? ?? ?????? ??? ????? ???? ???? ???? ????? ?? ????? ????? ?? ??? ????? ?????? ???? ?? ??? ?? ???? ?? ????? ???? ??.

Whetsell said, "This is basically the programming information for workpieces that have been previously processed by insert milling at the current stage. In DP's ESPRIT CAM software, we refer to it as' automatic programming of workpieces'." Whetsell said, "Programming the backward cutting tool in the X or Y axis direction becomes a bit tricky because you can't let the tool just retreat into the subsequent workpiece material, and you don't want to retreat the tool into the residual material generated by the previous cutting."

For example, to prevent vibration, a lower cutting speed should be used when the milling cutter overhangs for a long time. ?? ???? ?????? ???? ?? ????? ?? ???? ??? ?? ?? ???? ????? ????? ?????? ??? ????? ????? ??? ?? ????? ?? ????? ??? ??? ??? ???? ??? ?????? ?? ?? ????? ??? ?? ??? ?? ???? ????? ????? ?????? ???? ?? ????? ?? ?????? ???? ??.

Although general-purpose machine tools have the advantage of being versatile, using specialized machine tools is often a better choice in order to maximize productivity (and reduce deformation). ????? ????? ????? ?????? ?? ????? ???? ?? ???? ???? ????? ?????

When the tool overhang is large, the lateral milling force can cause excessive vibration, and slot milling can also effectively solve this problem. He also mentioned that another reason why manufacturers have become interested in plug milling is that with the revival of American manufacturing, some mold processing tasks are constantly returning from China to the United States.
