I will introduce the cutting speed and depth of cut in the setting of processing conditions.

MIST Corporation, which develops and sells "cutting catchers," introduces know-how on end mill cutting processing. There is a parameter called "tool rotation speed" that determines the "cutting speed." Additionally, there are three parameters that determine the "cutting amount" for "one-flute cutting," which are "tool rotation speed," "feed rate," and "radial cutting." Finally, there are two parameters that determine the tool's "cutting" against the material: "axial cutting" and "radial cutting." Eliminating overlaps, the parameters that determine the cutting conditions are four: "tool rotation speed," "feed rate," "axial cutting," and "radial cutting." In other words, setting the processing conditions involves determining the values of these four parameters: "tool rotation speed," "feed rate," "axial cutting," and "radial cutting." *For more details, please refer to the catalog or feel free to contact us.

basic information

【Setting Processing Conditions】 It is the determination of the values of parameters that define the processing conditions. The key factor is "cutting speed." This refers to the speed at which the tool cuts the material, and it is different from "feed rate." In end mill cutting, the tool cuts the material while performing circular motion due to its rotation, so the "cutting speed" is determined by the tool diameter and the tool rotation speed, which is set based on the tool's rotational speed. 【Cutting Speed】 The "depth of cut" is determined by the "tool diameter," "number of flutes," "tool rotation speed," "feed rate," and "radial depth of cut." Since "tool diameter" and "number of flutes" are specifications of the tool, the "depth of cut" is determined by the balance of the three parameters: "tool rotation speed," "feed rate," and "radial depth of cut." 【Depth of Cut】 This is the visible "depth of cut" that represents how much the tool is engaged in the Z direction and XY direction. *For more details, please refer to the catalog or feel free to contact us.
