Climb Milling versus Conventional Milling [ Sneaky CNC

Mar 22, 2018· – When cutting half the cutter diameter or less, you should definitely climb mill (assuming your machine has low or no backlash and it is safe to do so!) – Up to 3/4 of the cutter diameter, it doesn’t matter which way you cut – When cutting from 3/4 to 1x the cutter diameter, you should prefer conventional milling

Up Milling and Down Milling Video (Climb and Conventional)Here’s a good video overview of Climb Milling (Down) vs Conventional Milling (Up) that I did for my CNC Chef monthly column with Cutting Tool EnginWhat Is Climb Milling vs Conventional Milling (Down Milling vs Up Milling)?While many CNC’ers have gotten in the habit of always specifying climb milling, there are times to climb mill and there are times where conventionaAdvantages and Disadvantages of Up Milling and Down Milling (Conventional vs Climb)Advantages of Conventional Milling (Up Milling): 1 The width of the chip starts from zero and increases as the cutter finishes slicing 2 The tooUnder Certain Conditions Climb Milling Produces Negative Cutting GeometrySo far, you’ve probably gotten the idea that maybe you should always climb mill After all, it leaves a better surface finish, requires less energyTool Deflection and Cut Accuracy in Climb vs Conventional MillingHow does climb vs conventional milling affect tool deflection and accuracy? The following illustration contains small arrows (often called vectorsConsider Conventional Milling For Finish PassesThis one is counterintuitive for a lot of machinists who are trained for most of their careers that climb produces a better finish than conventionaConsider Conventional Milling When MicromachiningFor all the same reasons, but considering deflection is much worse micromilling, you should prefer conventional over climb milling most of the tim
