Grinding forces depend on the balance of stresses, as the abrasive grains shear the workpiece material. In metal cutting, there are three main zones of plastic shearing, all within the workpiece material. The principle of minimum energy states that the stress arrangement that requires minimum total energy is
Sharpening Basics Since sharpening is such an expansive topic in and of itself, I will leave the specific howto details for other posts. What you need to know in the context of fine tuning, however, is that any plane, new or old, requires initial sharpening and honing. At a minimum, new plane irons need to
Drill NomenclaturePoints• Elements of Drill Points • Lip Relief Angle – Varies with the diameter of the drill and hardness of the material – On larger diameters and drills for harder materials, lip relief is decreased to as low as 8° – Drills for soft materials and small diameters have high relief angles up to 24° – Lip relief angles are measured across the margin
