An A-also, so that A completes the upper right edge blade at right angles to the cutting movement. Obtained from Figure 1b. A blade when the tool turns any corner of the coordinate system in the xoy coordinate values ​​is calculated as: Ao = rcos ~ (I) yoA = rsin ~ (2) (time 0 = 0o a 45. When, = 0) At this point A square hole in the workpiece edge corresponds to the position of the right wall of the formula for calculating the coordinates:: b / 2 (3) m = btan ~ o / 2 (4) then the tool center coordinates calculated as: goo = Si a = b / 2 a 3aoasg ~ / 3 (5) yoo = ywA a shame btancp / 2 a ~ / 3asin ~ / 3 (6) under the principle of coordinate transformation. If this time around a mouth edge, and the tool table as long as the instantaneous center coordinates corresponding to the translational motion on it. = A Xoo, y a yoo, y shift values ​​for the table. Based on the above calculation method,ed hardy schuhe, the tool can be obtained at: roy each quadrant of the Cartesian coordinates of the instantaneous center formula for computing convenience, make the following assumptions: E = b/2F = mouth ∞ s. / 30: ds_n. / 3tt = btan ~ / 2 then A Blade in the first quadrant, the tool center coordinates for the table I. Xun Xiang 1, the center coordinates 0P'oD knife a 45 *- FIfG45. Yan Kuang 9 a 9 a twenty-CE-F D can be A blade in the same way the other three quadrants of the tool center coordinates the formula for the calculation of convenience for further simplification,mulberry norge, let: U = E-F = 1 1 C is a simplified calculation of the above was the decline of 2 Table 2o simplified tool center coordinates, Y axis for the table relative to the center of the tool by the plane moving coordinates. 'After a simplified tool formula instantaneous center coordinates to the computer program code has brought great convenience to lanthanum. 4 0 square hole cutter milling hard milling process diagram of Figure 2. In order to enhance edge strength edge may be convex triangular-shaped cutter into San, milling the square hole of the main program block diagram shown in Figure 3. 42 (Mold Industrial> 1998.No.8 General Mills 5 Conclusion 210 Figure 2 square hole if the above processing method is feasible, then by extension, like the rectangular hole,ed hardy schweiz, hexagonal, octagonal shaped hole milling as long as the software is designed to make some changes can be achieved. In the specific implementation process, the vision can be assisted rotation axis (the fourth axis) drive the tool rotates, movement. Another way to do a dedicated CNC tool milling head, the spindle servo motor with the spindle in the plane,franklin marshall pas cher, y direction of the servo motors of two linked to each other, so that you can ensure that a rotary movement of the tool in the At the same time, to achieve the shape of the workpiece profile milling holes. l bow began to side of the square hole of the workpiece jurisdiction jurisdiction of the tool diameter parameters Optional parameters into the hole to set the tool spindle speed borescope probe set the direction of degree of cutting the amount of limonene per Huan Zhu Lan + Yf =, 4 ..................!

To this end, after many years in a series of electrochemical machining of new technology research, including nonlinear electrolyte, pulsed current processing and feed processing vibration, so that the mold electrolysis processing significantly improved the precision, repeatability can reach O.05-0.1 hiss Ⅱ n. <br /> <br />相关的主题文章： <br /> <br /> <br /> abercrombie uk <br /> <br /> alexa mulberry <br /> <br /> ed hardy schuhe</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/xeon/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
