??? ????????? ????????? ???? ??? ?????? ??? ????????? ?????????? ????????????????? ??? ??? результат ???? ?? совместные ???? ???????????? ???? ??????????????????? Insertion milling (Z-axis milling) is a good example of machining. During insertion milling, the rotating tool directly cuts into the workpiece along the Z-axis direction and retracts the tool upwards along the Z-axis. Then, it moves horizontally along the X-axis or Y-axis direction for a certain distance, and performs vertical cutting that overlaps with the previous cutting part to cut more workpiece material. ????????? ?????? ???? ?? ???? ????????? ???????? ??? ????? ???????????? ????????

Bill Fiorenza, Product Manager of Ingersoll Tool Company's Mold Production Line, has stated that insert milling helps reduce cutting heat entering the tool and workpiece. 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. Fiorenza explained during the insertion and milling demonstration, "Usually, the temperature of metal chips is very high, and you can even bake a sandwich in the chip pile. However, when the insertion and milling process is completed, you can immediately place your hand on the workpiece and feel cooler to the touch." Reducing cutting heat can not only extend the tool life, but also minimize the deformation of the workpiece.

"You can first insert milling downwards, then move inward, and mill the root of the workpiece." Meyers believes that the limitation of insert milling technology is the difference between the actual cutting diameter of the tool and the diameter of the tool body. ??? ????? ???? ??? ???????????? ??????????????? ??? ???? ?????? ???????, ??? ?? ??? ???? ?? ?????? ??????? ????? ??? ??????? ???????? ???? ??? ????????????. ????? ??? ????????????????нг ????????? ???? ???? ????? ??????????нг, ??? ???????????????????? ???? ??? ???????? ????? ??? ???????? ???

Metal processing WeChat, the content is good and worth following. 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."

Insertion milling and high feed milling are metal cutting strategies with high productivity. The choice between using this technology or other milling strategies depends on multiple factors. ukuze ??? ??????? ?? ????????? ??? ??????, ??? ?? необходимо ?? ???? специализированные ????нг ??????? ??? ??????????????? ??? ?? ?????????????. ??? ???? ????, ???? ????? ?????? ??? ????? ?? ?????????? ??? ??? ???????? ?????????????? ?? сл??? ??????, ??? ???? ????? ?????? ??????? ????? ?????? ?????? ????? ?????? ??????? ??? ??????? ???????. ? ??????? ????????? ????? ?? ???????, ??? ?? ????????? ????? ?????-????????, ?? ??? ?????? ?? ???????????? ?? ?????-?????. ??? ???????????? ??????? ??? ???? ??????? ????????? ??? ??? ??????????????? ??? ????? ?????????????????, ???? ??? ???????? ?? lateral ?????????? ?????? ???? ??? ???????? ???? ???????, MAXline ????????? ???????????????? ???? ?????????? ?????, ?????? ??? ?? ?????????????? ????????? ??? ???????? ???? ?? ?????????????? ?????? ??? ????? ??? ????????????? ?? ??? ???????, "???? ?? ????? ????????? ?????? ?????? ??????? ?? ????? ??????????, ??? ???????????? ?????? ??? ???? ??? ???????????. ????? ??? ???? ???????? ?????????, ?? ??? ??? ????????? ?? ?????? ?? ??? ????????????. ????, ???? ?? ???? ?? ?????? ??? ????? ?????, ??? ???? ?????? ?????? ??? ???? ??? ???????????." ??? ?????????? ???? ??? ??????????? ??? ??????? ??? ??? ?? ?????? ?????? ??? ?? ???????? ???? 50mm ????? ??? ????? ????? ?????hang ?????? ??? ???? ????? ??????????. ??? ????? ?????? ??? ???? ??? ??????? ????? ????? ?????????? ?????? ??? ????? ???????? ?????? ???????. He said, "When the overhanging length of the cutting tool increases to 4 or 6 times the diameter, certain types of chatter will begin to occur. You can use high feed milling cutters and small cutting depths of 0.38-0.50mm to cope with these processing. You may also need to use some anti vibration tool structures, such as integral hard alloy tool holders and modular tool heads." Noble believes that a key factor in choosing a milling method is the daily machining tasks in the workshop. "For example, if you want to perform a large amount of 3D milling in your daily life and also want to do some insert milling, I would recommend using high feed milling cutters, which can also perform limited insert milling. But for cavity milling,... For milling, straight wall and groove milling, as well as large-scale processing, you should invest in purchasing specialized slot milling cutters

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). ?????? ??????????????? ???????????, ????? ?????????? ?????????? ??? ???????????? ?????? ????????
