| Abstract: | At the roughing of the helical flanks of the worms with frontal-cylindrical milling tools positioned perpendicular to the axis of symmetry of the half-product we can use tools of different diameters, with the mill position being different in each case. In this article the milling position is determined on the basis of the contact between the toroid surface of frontal-cylindrical milling tool and a helical surface, so that it remains the desired addition of processing. Determination of contact between the toroid part of frontal-cylindrical milling tool and the helical surface is done using coordinate transformations. The points thus obtained shall be brought in the axial plane, compared with the points belonging to the desired profile to obtain and determine the location of a mill at each crossing. The milling position at each crossing shall be determined by means of a program that compares the curve of contact between the helical surfaces brought into the axial plane of the worm with a straight line inclined with the angle of pressure of the studied worm located in the axial plane. For the cutting depth considered, the difference between coordinated on the OX of the curve and of the line, represents the movement of the tool along the axis of symmetry in the sense indicated by the sign of the difference. The program is designed in AutoLISP and the result of the calculated displacement is returned in AutoCAD. [ABSTRACT FROM AUTHOR] |
