Does the cutting force increase with the following why a increasing depth of cut B decreasing rake angle?
Does the cutting force increase with the following why a increasing depth of cut B decreasing rake angle? It is logical that the cutting force increases as the depth of cut increases and rake angle decreases. Deeper cuts remove more material, thus requiring a higher cutting force. What is rake angle in machining? Rake angle […]
