Sole Point Trimming Tools

A. Definition




It has only one cutting point or border.

Used for turning, boring, shaping or organizing operations.

These tools used on lathe, boring and shaper machine

B. Angles

Terminology of single level cutting application


Shank – the main body in the tool and used to hold in tool holder.


Flank- the area below or adjacent to revolutionary.


Confront – the very best surface along which the chips moves or slide.


Heel – the area of the flank and base of the application. It is curved portion at the bottom of the tool.


Nasal area – Is it doesn't point in which slide leading edge and foundation cutting edge intersect.


Bottom – a bearing area of the device when it is saved in tool holder or clamped directly inside the tool post.

Cutting edge – It is the edge on face of the tool which in turn removes the fabric from function piece.


Nose radius – That provide longevity and great surface end sharp level on nostril highly stressed, and leaves grooves inside the path of cut.


Tool Viewpoint – Tool angle have got great importance. The instrument with appropriate angle, reduce breaking of tool, cut metal more efficiently, generate less heat.

Cs - Aspect Cutting Edge Position

e- Part relief Viewpoint

Ce- End Cutting Edge Viewpoint

b- Back Rake Viewpoint

s- Area relief Viewpoint

Side Innovative Angle (Cs): It is the viewpoint between the part cutting edge and side of tool shank. The complementary angle of Side Cutting Edge Angle is called ‘Approach angle'.

End Revolutionary Angle (Ce): It is the perspective between end cutting edge and line typical to shank.

Side Relief Angle ( s): It's the angle between portion of area flank immediately below the side cutting edge and a range perpendicular for the base with the tool. End Relief Perspective ( e): It is the angle between portion of the end flank immediately under the end innovative and a line verticle with respect to basic of tool.

Again Rake Perspective ( b): It is the angle between deal with of device and range parallel to the base of tool scored in a airplane perpendicular to side leading edge. This is confident if the area cutting edge slopes downwards through the point for the shank and it is negative in the event the slope of side innovative is reverse. So , this angle shows the slope in the face of the application from the nasal area towards the shank.

Side Rake Angle ( s): It is the angle involving the face of the device and a line parallel to foundation of device and tested in a aircraft perpendicular for the base as well as the side leading edge.

The side rake is negative if the incline is towards the cutting edge and positive in case the slope is definitely away from the leading edge. This viewpoint gives the incline of deal with from the cutting edge.

C. Types according to shape

1 ) Right Palm - In the event viewed behind the tool down the length of the tool holder, at application designed to lower from remaining to proper.

2 . Left hand - A cutter in whose flutes turn in clockwise direction. three or more. Straight Rounded nose -- A carbide cutting equipment (also referred to as as lathe tools ) are used because metal reducing tools in machine retailers for...
