Which one of the following statements is correct about an oblique cut...
Oblique cutting:
Oblique cutting is a type of cutting operation where the cutting edge of the tool is inclined at an acute angle to the direction of tool feed. In this type of cutting, the tool moves in a diagonal direction relative to the workpiece.
Correct statement:
The correct statement about oblique cutting is option 'C' - the cutting edge of the tool is inclined at an acute angle to the direction of tool feed.
Explanation:
When the cutting edge of the tool is inclined at an acute angle to the direction of tool feed, it creates an oblique cutting action. This type of cutting results in several unique characteristics and considerations.
Key points:
- Angle between the cutting edge and the direction of tool feed: The cutting edge of the tool is inclined at an acute angle, typically less than 90 degrees, to the direction of tool feed. This angle determines the orientation of the cutting forces and chip formation.
- Components of cutting forces: In oblique cutting, there are three components of cutting forces acting on the tool: normal force (Fn), tangential force (Ft), and radial force (Fr). These forces are responsible for the material removal and energy consumption in the cutting process.
- Chip formation: In oblique cutting, the chip flows in a direction that is not normal to the cutting edge of the tool. The direction of chip flow velocity is determined by the inclination angle of the cutting edge. The chip flows along a curved path due to the oblique cutting action.
- Tool wear: Oblique cutting can lead to different types of tool wear compared to orthogonal cutting (where the cutting edge is perpendicular to the direction of tool feed). The wear patterns on the tool depend on the inclination angle, cutting speed, material properties, and cutting conditions.
- Tool geometry: The geometry of the cutting tool is designed to accommodate oblique cutting. The cutting edge is usually ground at an angle to create the desired oblique cutting action.
Conclusion:
In oblique cutting, the cutting edge of the tool is inclined at an acute angle to the direction of tool feed. This type of cutting results in unique chip formation, cutting forces, and tool wear characteristics. Understanding oblique cutting is essential for optimizing machining processes and tool performance.
