The following are detailed questions regarding the meaning of machining, divided into fundamental, technical, application, and current technology aspects.
1. Basic & Fundamental Definition
What is the general definition of machining in the context of manufacturing engineering? (Machining is a production process using machine tools that utilizes the relative motion between a tool and a workpiece to produce the desired geometry.)
What is the main objective of the machining process? (Transforming raw materials into precision workpieces.)
Why is machining called a subtractive manufacturing process? (Because material is removed/cut to form the final product, rather than molded or joined.)
What is the difference between conventional and non-conventional machining? (Conventional uses mechanical force (a tool), while non-conventional uses electrical/chemical energy.)

2. Machining Operations & Techniques
What are the three main machining operations? (Drilling, milling, and turning.)
What is meant by depth of cut in machining? (How deep the cutting tool enters the workpiece to produce chips).
What is the function of relative motion in machining? (It allows the tool to cut material accurately).
How does non-conventional machining, such as Electrical Discharge Machining (EDM), work? (It uses sparks to erode material).

3. Tools & Machines
What are the main types of equipment used in machining? (Lathes, milling machines, CNC machines, and turrets).
What is the functional difference between a lathe (turning) and a milling machine? (A lathe rotates the workpiece, while a milling machine rotates the cutting tool).
What is meant by Precision Machining? (A machining process with very high accuracy, often used for prototyping).
