What would be recommendation parameters (speed, feed, depth of cut) for machining cast iron FG 150 using inserts CCMT grade TTS on CNC Turning machine ?
Cutting conditions depends of the power and stifness of machine tool. The grade of insert is for which manufacturer? Kennametal, seco, mitsubishi?.
Which is the dimension of material to be cut (diameter and length)?. And the type of fixation?
Since Cast Iron FG 150 contains self lubricating properties,take a higher cutting speed for the insert CCMT grade TTS. The cutting speed formula will give the speed, feed and depth of cut as per the requirement of MRR.
Excuse me Sir. If TTS are an grade of Widia company, this grade is not good for turning cast iron (see attached file please). TTS is good for steel.
BHN is about 150. Feed need to be specified based on finish requirements. Start with about 0.3 mm/rev; and cutting speed about 280 m/min. Use appropriate grade of carbide.
