γ Back-off angle or clearance angle L w Length of the workpiece (not shown.
The clear difference between positive and negative rake angles is that for the positive rake angle,the leading edge of the cutting tool is behind the perpendicular of the material to be cut.While the tool leading edge is ahead or beyond the perpendicular for the negative rake angle.
obtuse angle
That's a reflex angle. 0 to <90 Acute angle 90 Right angle >90 to <180 Obtuse angle 180 Straight angle >180 to <360 Reflex angle 360 called Full circle
An obtuse angle.
An angle of 213 degrees is a reflex angle
You should know the angle of the cutting tool. You can use emery sharp cutting tool.
The clearance angle in machining refers to the angle between the cutting edge of the tool and the surface of the workpiece. Its primary function is to prevent the tool from dragging against the workpiece, which can cause excessive wear or damage. Additionally, an appropriate clearance angle enhances chip removal, reduces cutting forces, and improves the overall surface finish of the machined part. Properly designing this angle is crucial for optimizing tool performance and extending tool life.
An operation performed on a lathe that feeds a tool at an angle to the length of the workpiece in order to create a conical shape.
Short tapers on a lathe are produced by using a compound rest or by adjusting the tailstock angle. The workpiece is set at an angle, allowing the cutting tool to remove material progressively, creating a gradual taper. Additionally, the lathe can be set to a specific angle using a taper attachment or by manually adjusting the tool's position. This method ensures precise control over the taper's dimensions and length.

carriage is a part of lathe which means to be support cutting tool to give feed to cutting tool and control cutting action.
The centre lathe has only one coaxial tool, whereas the capstan has a rotating multi tool station with indexer and clutch.
Cutting tools for facing and outside diameter turning are set to an angle of 90 degrees to the bed. Boring tools are set to the same angle as the bed. Cutting tool tips are already angled to suit its purpose and there's usually no need for further adjustment. They can be set against the inside of the toolpost and fastened.
