Hi there
Need to do above slot under3 minutes cycle time. Currently I am using 7 mm 4F endmill on vmc BT50 in er32 collet holder.
Problem is the endmill i have has stickout ~5d ie 33 mm to be exact so it faces wearing out very soon.(have recently tried doing one hole on each side and taking 1.2 mm plunge on either side while removing material radially; it lasted 54 pcs)
Best I achieved was going progressive ramping (or zigzag downward path 25 cycles or 50 passes)with 0.5 mm depth of cut each side with feed rate 400 mm/min and 2000 rpm with TiN coated endmill 7 mm and stickout~30mm; it lasted 250 pcs nearly but couldn’t repeat the same performance again.
I am also keen on using HSM method but not by using the software as costs would go up.
Can progressive ramping by using carbide endmill 6or7 mm help achieve desired results or some hsm method with smaller dia square endmills with 4 flutes ?
