What are the different machining operations available?
A general manufacturing question assessing knowledge of subtractive processes.
Why Interviewers Ask This
Engineers must know how parts are made. This tests familiarity with standard machining processes like turning, milling, and drilling.
How to Answer This Question
List common operations: Turning, Milling, Drilling, Grinding, Boring. Briefly explain what each does (e.g., turning creates cylindrical shapes). Mention CNC vs manual.
Key Points to Cover
- Turning and Milling
- Drilling and Boring
- Grinding
- CNC integration
Sample Answer
Common machining operations include Turning for cylindrical parts, Milling for flat surfaces and slots, Drilling for holes, and Grinding for fine finishes. Boring enlarges existing holes to precise diameters. These operations can be performed manually or via CNC machines for high precision and repeatability.
Common Mistakes to Avoid
- Confusing additive with subtractive
- Missing basic operations
- Not distinguishing processes
