Precision Aerospace Machining and the seven wastes of lean manufacturing (part 4)

The 4th waste identified in lean manufacturing is Motion.  Motion concerns the ergonomics of the workers in a process and any unnecessary steps or movement that they have in the process.

To again look at the difference of a high mix / low volume precision aerospace machining facility and a high volume production we will see a difference in the ability to reduce motion.  In a high volume production environment you can count on a particular workstation being focused on a single task – even if that task is performed over a variety of individual parts, the motions and the ergonomics will be similar.  In a low volume precision machine shop, the task on one day may be entirely different than the task of the prior day.  While they will be related still – depending on the functionality of the machine at the workstation – the individual parts may require a significant difference in motion or handling.

To compensate for this changing process, CNC industries has designed it’s facility to accommodate a high mix of precision parts easily.  While the information and documentation may vary from one part to another, we have standardized the method of getting that information into electronic information stations which are uniformly located near the workstations.  Each worker in our facility may count on being able to get all necessary work instructions in the same way.

We have also standardized our machine setups with the tooling being handle off of the machine to eliminate unnecessary motion in the setup process.  The advantages of removing extra motion include more productivity, less stress on the people involved in the process, as well as lowered chances of errors and mistakes being made.  So even with a facility dedicated to fully custom machined parts and prototypes, we can easily remove unnecessary wastes.
