FF-Ti Machining

What is FF-Ti Machining?

When cutting hard-resistant alloys such as Ti-6Al-4V on big machines with over 1,000 Nm of torque, the strategy is pretty simple. Open a hole with a fast-feed cutter or a large-sized drill and then use a porcupine cutter to cut the main pocket.

But what about other-sized machines? Here, the limited allowed cutting force and thrust of axis feed put a stop to the strategies we can use. However, an FF-Ti strategy can help maximise the performance on these machines.
What is FF-Ti Machining?


For FF-Ti machining the basics to be followed are:
  • Reduce cutting force through shallow radial depth of cut
  • Cutting speed over 100/min
  • Long-flute end mill
  • Use holder through coolant
  • Spiral and circular tool path

Advantages of FF-Ti Machining

When we are talking about the profitability of a titanium cutting process, there are two main factors that need to be balanced: tool cost and cycle time.

The benefits we get with our FF-Ti strategy are as follows:
  • Improvement of average M.R.R. with the spiral and trochoidal path
  • Constant tool engagement angle for stable tool life
  • Longer tool life through using Makino’s recommended coolant
  • Maximum utilisation of smaller-sized machine such as the Makino a1nx series
