Designing for friction reduction and wear resistance (e.g., linear guide ways).
Deflection must be kept within micro-level limits to preserve machining accuracy. Mehta details the design of internal ribbing patterns (diagonal, box, or horizontal ribs) to boost structural rigidity without drastically increasing total weight. 3. Material Selection Standards
The core topics are systematically broken down across these major sections:
: Focuses on reducing friction and wear through the design of slideways (aerostatic, anti-friction, or liquid friction types) and the precision of power screws.
