The use of end mill with diameter 30-40% smaller than the width of the slot is recommended. The cutting conditions are based on CNC programming with medium dynamic speed. THYLPHOON With lower CNC dynamic speed, use the same cutting conditions or reduce the cutting speed Vc. With higher CNC dynamic speed, reduce the “T” value by approximately -30 -50% and apply the maximum available cutting speed Vc. ae R1 Cutter radius C-SD-TA R2 Half of slot width T Programming width of cut R2 ae Actual width of cut R1 LFTA Y (+) Y X (+) SUTA T HDSRSIL-LHSSS/CO G2 MDTA HF VH/UP MEF ALU MEX UH HENSSD/CMOIL-LHSSSP CBUARRRBSIDE PARAMETERS SUGGESTED WITH HIGH PRECISION WELDON CHUCK AND STABLE MACHINING CONDITION.
