Grind the Front Relief The first step in creating a tool bit is to grind the front relief. For most work, a relief angle of 10° works well. While you are grinding the front relief, you are also creating the front cutting edge angle. Make this angle about 10° also, so that the corner formed by the front cutting edge and the side cutting edge is less than 90°. Grind the Left Side Relief

CHAPTER 1- INTRODUCTION TO GRINDING

Grinding is a combination of rubbing, ploughing and cutting (actual chip formation with contribution of each being highly governed by grit geometry, work material characteristics, grinding loop stiffness and the grinding velocity The various stages of grinding and grinding force with grit depth of cut is shown in Figure 6. At a small grit penetration only sliding of the grit occurs against the workpiece.

form tools since material is easier to grind the special shapes. They may be mounted on the machine tool directly in the tool post. Smaller size solid bit are usually held in tool holder. This type of tool is tipped up to an angle from 15° to 20°. High speed steel and cast alloy tools are commonly categorized into solid type. The material used in solid bit is relatively cheaper than others.

Grinding the end face of the tool. The grinding rest was tipped to give the required end relief angle and the fence adjusted to give the front cutting edge angle. Again the front cutting edge angle was not important, although it is usually set to make the tip and less than 90 º. The relief angle is the critical one.

elements of woodturning Sharpening

a tool or any other heavy grinding operation, I rely on a 36- or 46-grit wheel. For the actual process of sharpening an edge, I prefer either a 60- (the new 54-grits are close enough) or 80-grit. My ideal setup is a 60-grit on the left side of my grinder (I am right handed; reverse this if you are a lefty) and a 36-grit on the other side. And finally, how hard should the stone be? Most stones ...
