What is the difference between oblique machining and orthogonal machining

Viva Differences. Comments are closed. In orthogonal cutting, the cutting edge of the tool makes right angle to the direction of feed motion.

Oblique cutting, the cutting edge of the tool is inclined to the direction of feed motion. There are only two components of force which are mutually perpendicular. The components include: cutting force and thrust force ; and can be represented by 2D coordinate system. This is operations done with turning movement.

Now to the discuss about Difference between orthogonal and oblique cutting or orthogonal vs oblique cutting. There is some important Difference between orthogonal and obliqur cutting :. Direction of cutting tool.. In orthogonal cutting is cutting edge of tool perpendicular to the direction of cutting edge or motion of tool. Chip flows.. In orthogonal cutting, Chip flows over the tool face And flow of velocity of direction is normal to the cutting edge.

In oblique cutting,the Chip flows on tool face and makes some angle with normal cutting edge.. Another name of orthogonal and oblique cutting..

In orthogonal cutting only two forces are acting on the tool that's why it's also called as two dimensional cutting. In oblique cutting there is three components of forces act at the cutting edge hence also called as three dimensional cutting. Chip formation. Discontinus chips are formed when Orthogonal cutting. In oblique cutting there is continuous chips are formed.

Tool life. Tool life of orthogonal cutting tool is lesser than than the oblique cutting tool. In oblique cutting the tool life is more better as compared to the Orthogonal cutting tool. These cuts are often performed on long, round pieces of food i. Orthogonal Cutting 2-D Cutting : the Cutting edge is 1 straight, 2 parallel to the original plane surface on the workpiece and 3 perpendicular to the direction of cutting.

For example Operations: Lathe cut-off operation, Straight milling, etc. Drilling is a oblique cutting because the angles of threads on drill bit are at an angle grater than 90 degree.

Some of machining processes are Milling, drilling, Broaching, Turning, shaping, planning, boring etc. Basic elements of Machining: The basic elements of machining are workpiece, tool and chip. For any cutting action, it is necessary to have relative motion between tool and workpiece.

Lecture 8. Metal Cutting Common cutting processes include sawing, shaping or planing , broaching, drilling, grinding, turning and milling. Metal cutting tools have a primary purpose of removing leftover material from a manufactured piece of metal by using the process of shear deformation.

There are mainly two types of metal cutting tools that are normally used; single point tools and multi-point tools. In metal cutting theory, all operations performed with the wedge-shaped tool when a layer of metal is removed in the form of continuous or discontinuous chip can be conventionally divided into two general cases, termed orthogonal and oblique cutting.
