document: Five-axis NC milling of ruled surfaces : optimal geometry of a conical tool The side milling of ruled surfaces using a conical milling cutter was studied . This is a field that has largely been ignored by research scientists , but it is much used in industry , especially to machine turbine blades . We first suggest an improved positioning with respect to the directrices of the ruled surface . As compared with the methods already developed for the cylindrical cutter , this positioning enables the error between the cutter and the work-piece to be reduced . An algorithm is then introduced to calculate error so one can determine the cutter dimensions -LRB- cone radius and angle -RRB- in order to respect the tolerance interval imposed by the design office . This study provides an opportunity to determine cutters with greater dimensions , thus alleviating bending problems during milling
