Practical guide to tolerances in mechanical design. How to set appropriate values, avoid over-tolerancing, and communicate dimensional requirements clearly in engineering drawings.

Introduction to design calculations for mechanical engineers. How to approach load analysis, choose safety factors, and perform basic structural calculations in practice.

How to select and use standard parts in mechanical design. Reduce cost, lead time, and complexity by leveraging standard components rather than designing custom parts.

Types of engineering drawings explained: assembly, part, and detail drawings—their roles, contents, and how each is used on the shop floor, from a practicing mechanical designer.

Engineering materials guide for mechanical designers: steel, aluminum, cast iron, stainless, plastics. Selection criteria based on load, temperature, cost, and machinability.

Essential guide to screws, bolts, and fasteners for mechanical designers. Thread standards, strength grades, tightening torque, and how to correctly specify fasteners in drawings.

Choosing the right bearing? This practical guide covers deep groove ball, cylindrical roller, and tapered roller bearings—with load, speed, and life-calculation tips from 20 years of machine design experience.

How to annotate engineering drawings correctly. Covers dimension placement rules, reference dimensions, tolerancing notation, and the most common dimensioning mistakes to avoid.

A guide to surface treatment options in mechanical design: plating, anodizing, heat treatment, and coating. How to choose the right process for function and environment.

Machining methods every mechanical designer should know—turning, milling, drilling, grinding—with design-for-manufacturability tips for each process and material.
