Abstract
本发明提供了一种测量钻铰锪一体刀具的锪窝刃起始距离的方法，其利用刀具预调仪进行测量，包括步骤S1、S2、S3、S4、S5以及S6。在根据本发明的测量钻铰锪一体刀具的锪窝刃起始距离的方法中，其利用刀具的直钻部分的直径d、标称锪窝角度CSA以及理论锪窝深度CSD之间的几何关系，得到标称锪窝角度CSA所对应的锪窝部分的直径D。然后选择刀具预调仪的X‑Z测量模式并进行有限次迭代测量，直至得到的锪窝刃距离CSln‑1与锪窝刃距离CSln之间的差值ΔCSl小于预设的一定值时，刀具预调仪停止测量，进而得到刀具的锪窝刃起始距离值。这种测量方法简单、可操作性强，且无需准确捕捉刀具锪窝刃起始点，即可得到准确的锪窝刃起始距离值，保证了锪窝刃起始距离的测量精度。
The present invention provides a method for measuring the starting distance of a countersink edge of an integrated drill-reaming-sinking tool, which uses a tool presetter to measure, including steps S1, S2, S3, S4, S5 and S6. In the method for measuring the starting distance of the spot facing edge of a drill-reaming integrated tool according to the present invention, it utilizes the geometric relationship between the diameter d of the straight drilling portion of the tool, the nominal spot spot angle CSA and the theoretical spot spot depth CSD , to obtain the diameter D of the spot facing portion corresponding to the nominal spot facing angle CSA. Then select the X-Z measurement mode of the tool presetter and perform limited iterative measurements until the difference ΔCS1 between the obtained countersink edge distance CSl n-1 and the countersink edge distance CSl n is less than a preset value , the tool presetter stops measuring, and then the starting distance value of the countersink edge of the tool is obtained. This measurement method is simple and highly operable, and it does not need to accurately capture the starting point of the spot facing edge of the tool to obtain an accurate value of the starting distance of the spot facing edge, which ensures the measurement accuracy of the starting distance of the spot facing edge.
