Title:
カッタ軸線の周りに回転可能な正面ホブ切りカッタヘッドに取付けられた同様の切削ブレードの前面割出し誤差を決定する方法
Document Type and Number:
Japanese Patent JP3958932
Kind Code:
B2
Abstract:
A method for determining front-face indexing errors of like cutting blades mounted in a face hobbing cutter head. The cutter head is rotatable about a cutter axis and the like cutting blades (e.g. inside cutting blades or outside cutting blades) each having a cutting edge and are arranged in a plurality of blade groups in the cutter head. The method comprises determining the angular position of the front face of one or more of the like cutting blades about to the cutter axis by rotating the cutting edge of one or more of the like cutting blades relative to an angular detecting means, such as a non-contacting probe. The measured front face angular positions are compared with respective theoretical front face angular positions and an angular difference, DELTA phi c, is calculated. A cutting blade front face index error, Fd, is then calculated and this error amount may be compared to acceptable limits and the blade may be replaced of the cutter scrapped if such limits are exceeded. Alternatively, an error normal to flank, N epsilon , (a radially measured component) may be derived from the calculated front face index error, Fd, and the position of the cutting blade may be axially adjusted by an amount, DELTA H, to effectively reposition the cutting edge radially to compensate for the influence of the front face index error.
