Marotta Scientific Controls, Inc. (Montville, New Jersey) designs, develops and manufactures valves, fluid control components and systems for commercial aerospace, space, industrial and defense applications.
Precision Machine Works, Inc. , located in Tacoma, Washington, is a manufacturer of complex machine parts and assemblies made to customer specifications.
There are many ways to schedule orders through a shop. Companies enlist everything from simple, visual signals to integrated, highly functional computer systems.
In last month's column, I described the value stream mapping process and how it is a natural first step in identifying opportunities to streamline the manufacturing process. Once you recognize the areas for improvement, you need to understand the lean manufacturing techniques that can help.
We certainly have managed to make many things overly complicated during recent years. For example, we have invested great sums of money in complex computer systems designed to tell us when to order parts.
Last month I described the Total Productive Maintenance (TPM) process and how companies can benefit from it. TPM involves creating a team charged with measuring machine performance, creating standards for preventive maintenance and inspecting equipment and keeping it clean.
More companies are embracing Total Productive Maintenance (TPM) as a means of keeping key machines up and running. TPM encompasses all of the key aspects of machine maintenance (reactive, preventive, predictive and so forth) with one key addition—it uses the skills of the machine operator to identify the need for maintenance early on.
Long setup times are still a reality in many companies. Setup is one of those activities that adds no value to a part and, therefore, needs to be as short as possible.
There have been countless times that I have visited machine shops and seen first-hand examples of perceived efficiencies that are not efficiencies at all. One of my biggest "pet peeves" is the "start the first operation on all the parts, then tear down and start the second operation on the same parts" approach to machining, which is often taken in the name of efficiency.
There is no doubt that many companies have experienced a drop-off in business during the past year. The economic downturn has affected almost every company in some way.
