The Milling Process – Definitions Cutting speedv c Indicates the surface speed at which the cutting edge machines the workpiece Effective or true cutting speed v e Indicates the surface speed at the effective diameter DC apThis value is necessary for determining the true cutting data at the actual depth of cut a pThis is a particularly important value when using round insert cutters

If doing this it will be necessary to calculate the feed rate and speed instead of using the chart Example using a 14” or 0125” bit – Straight V Carbide Tipped Endmill SB 13642 This bit is used for soft wood at a depth of 12” two times the diameter

May 05 2016 · Whether you are programming a 5axis CNC machine or turning handles on a 60 year old knee mill the numbers don’t lie However one very important lesson I have learned is to respect the variables Any common formula you are going to use in the machine shop will provide you with the information you need to approach the cut appropriately but remember to always treat that number as
