Grinding Flashcards
Q: What is cylindrical grinding?
A: A process of grinding the external or internal cylindrical surfaces of workpieces, primarily used to smooth and finish cylindrical parts.
Q: What is surface grinding?
A: A grinding process where a spinning wheel covered in rough particles cuts chips from a surface, making it flat or smooth.
Q: What is infeed grinding?
A: A form of centreless grinding where the workpiece is fed into the grinding wheel and support plate, but is not passed through, allowing for grinding on specific areas of a part.
Q: What is through-feed grinding?
A: A process where the workpiece passes completely through the grinding wheel and support plate, primarily used for long and thin cylindrical parts.
Q: What is centreless grinding?
A: A machining process that uses abrasive cutting to remove material from a workpiece without requiring workpiece mounting.
Q: What is face grinding?
A: A type of surface grinding used to produce flat surfaces on parts.
Q: What is rake angle in machining?
A: The angle formed by the cutting tool’s face and the plane perpendicular to the workpiece surface, influencing chip flow and cutting forces.
Q: What is the difference between positive and negative rake angles?
A:
Positive rake angle reduces cutting forces, improves surface finish, and reduces power consumption but decreases tool strength.
Negative rake angle increases tool strength and stability, suited for harder materials but requires more force.
