Prochem Turnkey Projects Interview Questions, Process, and Tips

GD&T stands for Geometric Dimensioning and Tolerancing, a system for defining and communicating engineering tolerances.

• GD&T is a symbolic language used on engineering drawings to specify the allowable variations in form, size, and orientation of features.

• It helps ensure that parts fit together properly and function as intended.

• GD&T uses symbols such as concentricity, flatness, perpendicularity, and position to communic...read more

Surface finish symbol indicates the type of surface treatment required on a part for manufacturing purposes.

• Surface finish symbols are typically found on engineering drawings to specify the type of finish needed on a part.

• The symbol consists of a horizontal line with various geometric shapes and numbers that indicate the required finish.

• Examples of surface finish symbols include Ra for roughness average, Rz for maximum...read more

A CNC machine works by using computer programs to control the movement of the machine's tools and workpiece to create precision parts.

• CNC machines use computer programs to control the movement of the cutting tools and workpiece.

• The programs are created using CAD/CAM software and converted into G-code instructions.

• The machine reads the G-code instructions and moves the tools along the specified paths to cut and shape th...read more

Overall equipment effectiveness (OEE) is a measure of how well a manufacturing process is performing.

• OEE is calculated by multiplying availability, performance, and quality rates.

• It helps identify areas for improvement in production processes.

• Example: If a machine has an availability of 90%, performance of 95%, and quality of 98%, the OEE would be 83.7%.
