Since Cast Iron FG 150 contains self lubricating properties,take a higher cutting speed for the insert CCMT grade TTS. Speeds & Feeds for Knurling. 2×1350=270mm/min The spindle feed is 270mm/min. The 26-feet-per-minute feed. Thus, total power consumption is reduced. This value is necessary for determining the true cutting data at the actual depth of cut (a p). SOLUTION : V=80 m/min f=0. Cutting Speed 3. Before using a cutting tool, it is necessary to understand tool cutting speeds and feed rates, more often referred to as "speeds and feeds. Where chipload is the amount of material cut per tooth (feed per tooth). With the introduction of the Formulas App from WNT, calculating cutting data has never been so quick, easy and unbelievably practical. Cutting conditions are determined by the machinability rating of the material. Cutting Speed The cutting speed (v) of a tool is the speed at which the metal is removed by the tool from the work piece. Tool Life estimation. Speed and Feed Calculator for Drilling and Milling,easyspeedsandfeeds. 75-inch cutting depth and because safety should always be concern number one with power tools, a lock-off trigger switch to prevent accidental startups.
