Description
【発明の詳細な説明】 本発明は2次元輪郭の切刃を回転させて、平面。[Detailed description of the invention] The present invention rotates a cutting edge with a two-dimensional contour to create a flat surface.
柱面・回転面等を加工する回転工具に関するもので、そ
の目的とするところは、再研削と組立との容易な切刃に
よって騒音振動の少い加工を実現することにある。This relates to a rotary tool for machining cylindrical surfaces, rotating surfaces, etc., and its purpose is to realize machining with less noise and vibration by using cutting edges that are easy to re-grind and assemble.
本発明はかんな盤・電動かんな・フライス盤などの工具
に適用できるが、特に平板加工の木工かんな盤への適用
が重要であるので、まずこの場合を例にとって実施の態
様を説明する。Although the present invention can be applied to tools such as planing machines, electric planers, and milling machines, it is especially important to apply it to woodworking planing machines for flat plate processing, so the embodiment will first be described using this case as an example.
かんな盤における切削をなめらかに行わせ騒音を低減さ
せるにはヘリカル刃を用いるのが有効とされているが、
刃の製作に困難があり高価であるばかりでなく、刃の再
研削に特別の設備と技術および時間を要するのでコスト
高になり、現場で歓迎されず、普及が妨げられている。It is said that using a helical blade is effective for smooth cutting and reducing noise on a planer.
Not only is it difficult and expensive to manufacture the blade, but regrinding the blade requires special equipment, technology, and time, making it expensive, making it unpopular in the field, and preventing its widespread use.
本発明はこの欠点を除き、再研削と組立が簡単でかつヘ
リカル刃とほぼ同様の性能と効果を得る回転工具を提示
するものである。The present invention eliminates this drawback and provides a rotary tool that is easy to regrind and assemble, and which provides performance and effectiveness substantially similar to that of a helical blade.
さて平面を切削する回転かんなの刃先は円筒面を描く。Now, the cutting edge of a rotary planer that cuts a flat surface draws a cylindrical surface.

The circles where the axes 01 and 02, the cylindrical surface 3 (radius R) drawn by the L1 cutting edge, and the end surfaces 1 and 2 intersect are 10 and 20, respectively.

よびδ。Assuming that Ogi, Ageo te-3, and Mr. 2 and Dogouki, the line era 1 and A2Gt are parallel, one plane 6 containing both lines is determined. The intersection line 7 between this plane 6 and the cylindrical surface 3 drawn by the cutting edge forms an elliptical arc. This elliptical arc 7 is the contour of the cutting edge of the cutter 101, the plane 6 is the flank of the cutting edge, and the elliptical arc 7 is the conductor surface 8 (its generatrix is parallel to A, H).
Consider a knife with a rake face of 0.0. The cutting edge draws a cylindrical surface when rotated around the same time, so if a relative linear feed motion is applied between the plate material in contact with this and the tool axis, it is possible to cut the correct plane, and the cutting situation is similar to that of a helical blade. Become something. However, the rake angle perpendicular to the axis is the end face 1 o/bo C hole sin α1-□, tooth α2 =] 02Hz = Or H++ W tan β Therefore α2>
α! Therefore, the rake angle α changes along the cutting edge, and there is a drawback that the rake angle cannot be kept constant like a helical blade. It is not necessary to keep the rake angle α perpendicular to the cutting axis constant, and it is acceptable as long as it is within a practically allowable range. Therefore, the axis-perpendicular clearance angles δ1 and δ at end faces 1 and 2.

0° − γ − α2 (2), the clearance angle δ also changes along the cutting edge. α and α2 must be determined by taking into account the value of the clearance angle. In general, the cutting force is The larger the angle, the smaller the cutting edge angle, and the larger the relief angle, the smaller the cutting edge angle.

2C。Since the rake face has a cylindrical surface that is equilineal to the contour of the cutting edge, when re-grinding the cutting edge, the correct contour of the cutting edge will always appear just by sharpening the flat flank surface. When assembling the knife to the planer body, make sure that the cutting edge is in the correct position.
The back surface 9 of the rake face is a plane parallel to the generatrix of the rake face 8, and in order to touch the opposing flat surface 9' on the side of the planer body and to set the height of the cutting edge correctly, set it close to the end of the flank. A tangent plane part 14 that is in close contact with each other in parallel is provided on the plane body side, and when assembling after re-grinding, the flank surface 6 is moved in parallel by the depth of re-grinding while suppressing the movement of the cutter 101 in the axial direction. Press the surface 6 against the opposing flat surface No. 14 on the plane body side. The back surface 9 of the rake face is the rake face 8 (elliptic cylindrical surface)
It also serves as a reference surface when finishing. In addition, since the back surface of the flank (bottom surface 11 of the cutter) is used as a reference surface when grinding the flank 6, it is preferable to make it a plane perpendicular to the generatrix of the rake face (a horizontal plane in the figure). Then, the cross section of the cutter will be quadrilaterals A, B, C, D and A, B on both end faces 1 and 2, respectively.

You can re-sharpen knives that have been stored on the shelf.

Cutting curved surfaces is a breeze.
