Effective workholding is the foundation of accurate, safe, and repeatable manufacturing processes.
Whether used in machining, assembly, or testing, clamps and workholding devices play a critical role in controlling movement, resisting external forces, and protecting both the workpiece and the operator. Poor workholding design can lead to part distortion, scrap, safety risks, and reduced productivity.
This comprehensive e-handbook from Reid Supply provides engineers, machinists, and designers with a practical guide to selecting and applying clamps and workholding components for heavy-duty industrial applications. The guide goes beyond product selection to explain the physics, forces, and design principles that influence workholding performance.
Drawing on real engineering fundamentals, the handbook bridges the gap between theory and practical application.
You will learn how:
- Clamping and workholding forces interact during machining, assembly, and testing
- Reid Supply explains torque, vectors, and force analysis in practical terms
- Degrees of freedom affect part stability and positioning
- Proper locating must occur before clamping is applied
- Cutting forces influence required holding force calculations
- Toggle clamps, strap clamps, pneumatic, and hydraulic systems differ by application
- Maximum holding capacity determines safe clamp selection
- Clamp positioning directly impacts accuracy and repeatability
- Human factors influence safety, ergonomics, and cycle time
- Feedback and sensors improve automated workholding reliability
The guide walks readers through essential topics such as jig versus fixture design, locating strategies, machining force calculations, and the relationship between clamping force, exerting force, and holding force. Clear diagrams and examples illustrate how misaligned forces can reduce holding effectiveness or cause part movement.
The handbook also provides detailed comparisons of common workholding devices including toggle clamps, straight-line clamps, strap clamps, grippers, rest pads, vises, and power workholding systems. Selection tables outline pros, cons, holding capacities, and typical use cases to help engineers choose the right solution for each application.
Special attention is given to safety and ergonomics. The guide references industry standards and explains how handle design, operator strength, accessibility, and feedback mechanisms affect usability and long-term reliability in both manual and automated environments.
This whitepaper is designed for manufacturing engineers, tooling designers, machinists, maintenance teams, and operations leaders who want to improve fixturing performance, reduce risk, and increase process consistency.
