DC 0,75×DC S 9 TECHNOLOGIES Plunge Milling (Slotting) For this technology, you will find recommendations for the maximum permitted radial depth of cut for a given tool group. In this case, tool overhang L plays a vital role. It is therefore recommended to use a higher overhang (L/DC > 4) when creating wider recesses and to adjust engagement conditions in line with the following figures: Contour milling 8755 < L/DC = 4 > 8 967 4 5 321 ae 4312 ae 0,75×DC 1,5 × ae 0,5×DC S S Slot milling ae ae Shoulder milling In shoulder milling, the mutual offset of paths should also not exceed ¾ of the milling cutter diameter (and should be gradually decreased towards the corner). When creating programmes for this technology, you should avoid passes over already machined surfaces (bottom). In other words, we do not recommend using a so-called drilling cycle. When selecting engagement conditions, make sure that more than one tooth is engaged at all times. We also recommend gradually reducing the axial depth of cut (plunge depth), i.e. creating a "staircase" structure. Also keep in mind that plunge milling requires the use of lower speeds and feeds per tooth compared to traditional methods. 774
