May 21, 2019 · Calculating time for finish turning and boring operations done on a CNC turning center are also more complicated. To do it perfectly, you must treat each segment being machined separately. For this reason, many quoting people will try to come up with an "average" diameter on which to base the rpm calculation.
cycle time spreadsheet. Excel Details: 2711.Originally Posted by ACE323. Hey all. We recently visited DMG in Chicago and they gave us a cycle time estimate for a part we are currently running on 1 of our lathes.Looking at it, I realized it was an excel file.It broke down the operations (ex.turn, cutoff, drill,etc.) gave a cuttime for each and added them up for a total cycle time on lathe cycle ...
π (3.14) : Pi. n (min-1) : Main Axis Spindle Speed. (Problem) What is the cutting speed when main axis spindle speed is 700min -1 and external diameter is Φ50 ? (Answer) Substitute π=3.14, Dm=50, n=700 into the formula. vc= (π×Dm×n)÷1000= (3.14×50×700)÷1000. =110 (m/min) Cutting speed is 110m/min.
