Course content, instructors and details subject to change. This listing was last updated on March 1, 2013.
Date/Time: Wednesday, May 8, 2013, starting at 8:00 a.m. For details, see course agenda
Course Chair: Dr. Fred Passman, BCA, Inc.
Course Description: Once a metalworking fluid (MWF) has been qualified for use in an application, its performance depends on successful fluid management. In turn, successful fluid management depends on a fundamental understanding of the factors that work against fluid life and fluid performance, as well as cost effective strategies for preventing these factors from causing MWF failure. MWF 250 is designed to meet both of these needs. It covers primary failure mechanisms, including: the effect of contaminant particle size, water quality, microbes and oil contamination. It also presents recommendations on how best to prevent each of these factors from destroying MWF performance and shorting MWF functional life. The instructor team is made of internationally recognized experts who have an average of more than 30 years MWF management experience. This course is designed for those involved in developing, working with and using metalworking fluids.

We’ll also discuss how this course fits in with STLE’s Metalworking Fluid Management Training Program which now includes five metalworking fluid management courses.

Metal Worked and Particle Size Considerations
Overview: The type of metal being machined can significantly affect the stability of contain types of metalworking fluids. The accepted cause is that certain metals have three positive charges while some metals have two positive charges. In addition some metal working processes generate very small particles, while other processes generate long string-like chips. The smaller particle size generates more surface area per mass of metal removed and thus the available reactive surfaces of the metal increases.

Filtration, Gravity, Vacuum or Pressure
Overview: Filtration of metalworking coolants has a major effect on the quality of the finished product and life of the coolant itself. This module will discuss the different filter barriers, disposable media and non-disposable media systems, system operation covering different styles of separation and filtration for metalworking coolants; with their individual characteristics and performance levels, and a discussion about cost versus performance for differing systems and customer requirements or expectations.

Water Quality Issues and Control Practices
Overview: Water comprises 90-95% of most water-based metalworking fluid mixes. The quality of the water is therefore critical to the performance of the fluid. Sources of water, effects of the mineral content, measurement methods of various ions, and water treatment methods will be presented in this module.

Extraneous Oils, Contamination Effects and Control Practices
Overview: These extraneous oils are commonly referred to as tramp oils. They have an extremely detrimental effect all types of metalworking fluids. There are adverse chemical reactions with the additive packages in some type of tramp oils. Biological growth is increased since some types of tramp oils contain biological nutrients. Removing these oils becomes very difficult since the oils are mutually soluble with components of the metalworking fluids. This module will discuss tramp oil effects and removal practices.
Instructor: John M. Burke, Houghton International
Biography: See above.
Microbial Concerns and Controls
Overview: MWF microbes contribute to both fluid performance and employee health problems. In both cases, there is substantial overlap in the data pointing towards biological and non-biological causes. IN this module we’ll discuss how to recognize when microbes are either the primary cause or a significant contributing cause of a problem. We’ll also address the primary industrial hygiene and fluid management strategies that will minimize the risk of microbial contamination problems.
Foam Issues and Controls
Overview: Foam in a metal removal fluid and neat oil type products are influenced in many ways; chemistry of the product, the process it is used in, the configuration of the delivery/return system, contaminants that entry the system or fluid, water type, the tooling type that is used in the process, etc. This module will be exploring all of these areas and more based on recognizing, minimizing, and identifying the failure routes and what can be done in an anticipative manner to reduce issues to do with unwanted foam.

Corrosion: Cause, Concerns and Controls
Overview: Corrosion can be a major issue as it affects the parts produced, but it also can have some major affect on the equipment and automation in the process leading to some very costly operating cost situations. Metal removal fluids and neat oil type products should generally be built at a minimum with in process corrosion control properties. This module will be focused on the mechanisms to do with corrosion and what the user can do in an anticipative and predictive manner to avoid such costly situations from a part and process standpoint; type of product, what type of corrosion, what is the corrosion protection needed, chemistry of different type of metal removal products, contamination vehicles, metal types, etc.
Instructor: John Steigerwald, Etna Products
Overview: Metalworking fluids come in contact with many materials that are part of the work environment. These include machine tools and filters, part storage and transfer equipment and air handling devices. The components of this equipment (metals, plastics, elastomers, paint, etc) can be made of many different materials that may or may not be compatible with the components of the metalworking fluid. In this module we will review these compatibilities as well as solutions and prevention of problems.

Metal Removal Fluid Root Cause Analysis
Overview: Most commonly, observable problems or effects are the result of the convergence of two-or more causes. In recent years, the concept of root cause has often been misunderstood to mean a single, identifiable factor that is responsible for the undesired effect. More correctly, root cause should suggest an image of the complex root system that sustains a tree. Root Cause Analysis – RCA – is a powerful set of tools for helping fluid managers to better understand how multiple factors interact to cause and end result. During this module, we’ll look at how asking the wrong diagnostic question can prevent you from solving an operational problem. We’ll then look at two tools for doing RCA: fishbone diagramming and cause and effect diagramming. We’ll examine how the cause and effect diagram can focus troubleshooting efforts and improve overall understanding of MWF system operations.
