What is the basic difference between orthogonal machining and oblique machining?
Difference between Orthogonal and Oblique Cutting
| Orthogonal cutting | Oblique Cutting |
|---|---|
| The cutting edge is larger than cutting width. | The cutting edge may or may not be larger than cutting width. |
| Chips are in the form of a spiral coil. | Chip flow is in a sideways direction. |
What is oblique cutting?
The roll cut (also known as the oblique cut) is a specific type of knife cut used to create pieces of food with two angled sides. These cuts are often performed on long, round pieces of food (i.e. carrots and parsnips) and add visual appeal to a dish.
Which of the following is an example of orthogonal cutting?
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.
Which of the following is an example of oblique cutting?
Drilling is a oblique cutting because the angles of threads on drill bit are at an angle grater than 90 degree.
What are the elements of cutting process?
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.
Which is an example of metal cutting process?
Lecture 8. Metal Cutting Common cutting processes include sawing, shaping (or planing), broaching, drilling, grinding, turning and milling.
What is the main purpose of metal cutting?
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.
What are two popular metal cutting theories?
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.
How is metal removed in metal cutting?
The metal in front of the cutting tool rake face gets immediately compressed first elastically and then plastically. The actual separation of the metal starts from the cutting tool tip as yielding or fracture, depending upon the cutting conditions. Then the deformed metal (called chip) flows over the tool (rake) face.
When a drill cuts through a metal piece it performs motion?
Explanation: Turning is done when motion of job is rotary and motion of cutting tool is forward translating. In turning operation, metal is removed from the outer diameter of the surface. It is very basic operation. 2.
