Autocad Mechanical Draughtsman Interview Questions and Answers

Different machines are used for various processes like turning, step cutting, and creating holes on the surface of a bar.

• For turning: Lathe machine is commonly used to rotate the workpiece while a cutting tool removes material to create cylindrical shapes.

• For step cutting: Milling machine is often used to remove material in steps to create precise shapes and sizes.

• For creating holes on the surface of a bar: Drilling machine is used to drill holes of various sizes and depths o...read more

Machining symbols are used to indicate specific machining operations on a part, while GD&T (Geometric Dimensioning and Tolerancing) is a system for defining and communicating engineering tolerances.

• Machining symbols include features like holes, threads, and surface finishes, and are typically shown on engineering drawings to specify the required machining operations.

• GD&T uses symbols, such as position, concentricity, and perpendicularity, to define the allowable variations in...read more

Machining processes are a group of operations used to shape and finish materials through the removal of material.

• Milling: cutting and shaping materials using a rotating cutter

• Turning: rotating a workpiece on a lathe while a cutting tool shapes it

• Drilling: creating holes in materials using a rotating drill bit

• Grinding: using an abrasive wheel to remove material and create a smooth surface

• Broaching: removing material with a specialized tool called a broach

• Electrical Discharge M...read more
