Which procedure is recommended for handling small items on a machine?

Utilizing jigs or fixtures is a recommended procedure for handling small items on a machine because these devices offer a stable and secure method for positioning and manipulating components. Jigs and fixtures enhance precision and consistency in machining operations by ensuring that small parts are held in place, reducing the risk of accidental movement or damage during processing. They also free the operator's hands, allowing for increased focus on the task and minimizing the chance of injury.

On the other hand, options such as using bare hands can lead to issues such as slipping or misalignment, particularly when dealing with small or delicate items. Holding items with a towel may not provide the necessary control or precision, as the towel itself can introduce additional difficulty in grasping and maneuvering items correctly. Keeping small items loose on the table poses a significant risk of losing track of them or causing contamination and damage, which can lead to errors in processing or assembly. Therefore, the use of jigs or fixtures is the most effective and safe approach.
