This flexibility helps manufacturers respond to changing orders rapidly, supporting just-in-time production and improving overall efficiency. Additionally, soft jaws can be made from materials that minimize part damage, which is crucial when handling delicate components.

However, there are downsides to relying solely on soft jaws. They may not hold parts as securely as dedicated fixtures, especially during high-stress operations like heavy machining or welding workholdings. This security concern can lead to variations in part accuracy, increasing scrap rates. A machine shop that invested in soft jaws for all applications reported a 15% increase in part rework, while those using dedicated fixtures maintained tighter tolerances. Ultimately, the decision to use soft jaws versus custom workholding solutions requires a careful assessment of the specific requirements and trade-offs within each manufacturing scenario.

4 Essential Factors in Fixture Selection

When selecting fixtures for any project, consider the type of material you'll work with. Compatibility is key; certain metals might require specific types of custom workholding to ensure precision.
