Gemsons Precision Engineering Interview Questions, Process, and Tips

Q1. What is ru outout?what is concentricity?
Ans. 
Ru output is a measure of the surface finish of a part. Concentricity is the measurement of the center point of a feature relative to its axis.
• Ru output is a measure of the roughness of a surface, typically measured in microinches or micrometers.

• Concentricity is the measurement of how well the center point of a feature aligns with its axis.

• For example, in a cylindrical part, concentricity would measure how well the cen...read more

Q2. What is relief angle and rack angle? What i counter bore?
Ans. 
Relief angle is the angle between the flank and the perpendicular to the cutting edge. Rack angle is the angle between the tooth face and a plane perpendicular to the cutter axis. Counter bore is a cylindrical flat-bottomed hole that enlarges another hole.
• Relief angle is important for reducing friction and heat buildup during cutting operations.

• Rack angle is important for determining the shape and size of the teeth on ...read more

Basics MCQ for machining process. It's too easy to solve.

Q1. Offset of machining.
Ans. 
Offset of machining refers to the adjustment made to the position of the cutting tool to achieve the desired dimensions and surface finish of the workpiece.
• Offsets are used to compensate for tool wear, tool deflection, or inaccuracies in the machine setup.

• Common types of offsets include tool length offset, tool radius offset, and workpiece offset.

• Offsets are typically adjusted in the CNC machine control panel or throug...read more
