About the Instructors The seminar features industry experts for providing valuable insights into a full range of operations critical to the gear process engineer. One of the most pressing challenges facing American manufacturing today is the shortage of skilled people for any number of critical roles. This is certainly the case with the gear industry. While strides are being made to prepare young people for vocations in manufacturing, the fact that a significant amount of expertise will be leaving the workforce as Baby Boomers retire, threatens the collective expertise of this critical industrial sector. For this reason, Arvin Global Solutions (AGS) is dedicating our efforts to develop and facilitate training opportunities with the primary goal of transferring the knowledge of today's gear industry experts to the next generation.

About the Seminar The upcoming seminar, taking place on March 7, 8, and 9, 2017, will be held at the Northern Illinois University - Naperville Conference Center at 1120 E Diehl Rd #150 Naperville, Illinois. Gear Process Engineering is a critical role in the gear manufacturing process. A great deal of knowledge and experience is required to successfully perform this function. However, formal training for this skill set is not available through traditional academic offerings. The result is a shortage of engineers for this role in gear manufacturing. Left with limited options for recruiting skilled, experienced process engineers, gear companies are often faced with the necessity of internally training employees from their organizations. By taking this route, companies must encroach on the valuable time of existing staff to bring these trainees up to speed, and this learning curve can take many months, if not years, before the trainee is able to work efficiently on their own. For this reason, AGS is offering the three day seminar to provide engineer trainees with a solid overview of the principles involved in processing a gear for the manufacturing process. This will involve lectures as well as hands on experience through exercises. The trainee will also receive a training manual that documents all of the material presented during the seminar. Upon completing the training the trainee will be able to perform simple processes, while having an awareness of issues of concern, such as operational sequences, proper manufacturing tolerances, heat treat distortion, locating surfaces, and quality. When the trainee returns to their company, they will require less direct training from engineering staff resources. In addition, in the event that internal resources are unable to spend adequate time with the trainee, AGS offers a follow up mentorship program. A specifically assigned mentor will be available at an hourly rate to answer questions, review processes, provide cost reductions suggestions, and make recommendations on any additional training required by the trainee. www.arvinglobalsolutions.com 1808 Ogden Ave, Lisle, IL 60532 (800) 815-2303 Contact@ArvinGlobalSolutions.com
Course Topics The following is an outline of key topics that will be presented during the Gear Process Engineering Training Seminar. Session 1 Introduction (4 hours) Presenter: Bruce Roberge DAY 1 1. The role of the Process Engineer Creating an efficient path from blueprint to finished part The Process Engineer must know the type and capability of the plant s equipment. COMMENT: To assist the trainee in understanding this concept, they will be presented with a sample copy of a Processing Capabilities Worksheet. This will contain a list of the general types of machines used in gear manufacturing with the general capabilities for size and tolerances which can be maintained, to be used when they work through a sample process exercise during Day 3 of the training. Equally valuable, each will be given a digital copy of an Excel spreadsheet that they can use later for work at their company to document their available machines and capabilities. The first question to ask: Have we manufactured a similar part before? Processing to make a profit (less cost with good quality) Don't over look vital info on the PO or specs on the print What does the Process Engineer need to look for before starting the processing? (Note: the trainee doesn t have to understand all technical aspects.) Evaluating the blueprint Types of gear spur, spline, helical, bevel, worm, etc Geometry configurations which generally cause machining problems (highlights only) Configuration and potential heat treat distortion concerns (highlights only) Type of Material Bar Stock or Forging Heat Treatment required o Through hardening o Induction hardening o Carburization & hardening o Vacuum o Nitriding o Hardened areas vs. non hardened areas Gear Process Engineering Training Course Outline Course Topics Page 1

Operational Sketches Typically operational sketches are provided for critical operations. Session 2 Turning, Milling, and Drilling (3 hours) Presenter: Matt Mondek 1. Turning Turning is the first step in the process where the part begins to take shape. Turning should be thought of as the foundation of the part as it impacts many subsequent operations. Discussion topics should include: Considerations for machining from Bar or Forging (chucking diameter needed) Designate chucking (locating) surfaces for turning both sides Typical dimensions and tolerances for turning both sides such as: o When to leave stock for grinding and heat treat distortion and why o Where to have close tolerances when open tolerances are permitted on the blueprint and why o Required locating surfaces for post turning operations o Dimensions to be held for compensation of heat treat distortion o Will further machining be necessary after heat treat due to distortion? 2. Milling Locating (chucking) surfaces Basic dimensions and tolerances Special tooling required Surface finishes requirements or extreme tolerance Any timing required Will further machining be necessary after heat treat due to distortion? 3. Drilling Locating (chucking) surfaces Gear Process Engineering Training Course Outline Course Topics Page 2

Photos of each type of gear will be provided as orientation. The trainee will be told to refer to the gear data on the blueprint for specifics. 2. Gearing Types Spur Spline (external and/or internal) Helical Herringbone Straight bevel Coniflex Spiral bevel Hypoid bevels Worm 3. Insuring that there is proper cutter clearance. 4. Based on the blueprint gear data or tooth surface finish, determine if the gear teeth require lapping, honing, or grinding. 5. If the gear teeth require grinding, considering the geometric configuration and part size, and determining the amount of stock to be left on the gear teeth. For grinding, typically 0.005 to 0.007 (0.127 to 0.178 mm) stock per flank 6. Determine if work holding tooling is available is this is the responsibility of the process engineer? 7. Determine if cutting tools are available or must be ordered is this the responsibility of the process engineer? 8. From the gear data on the blueprint, determine the type of machine required is there cutter clearance requiring shaping or smaller diameter cutter 9. Deburring gear teeth before heat treating 10. Broaching Basic tooling required and locating surfaces Surface Finish requirements or extreme tolerancing. Timing Requirements Will further machining be necessary after heat treat due to distortion?

Session 4 Heat Treatment (4 hours) Presenter: Al Swiglo 1. If the carburizing and hardening process is required, are there areas to be nonhardened. Using copper plating or other stop off materials to be applied to various areas as indicated on the blueprint. 2. Basic overview of various types of heat treating equipment Through hardening Induction hardening Carburizing and Hardening Die quenching Vacuum Nitriding General guidelines as to expected size changes and distortion due to heat treatments and ways to minimize or predict them 3. Basic discussion on determining if die quenching is required is tooling required or quench plug 4. Are Temper, draw, and deep freeze required in a spec? Is this decision left up to the heat treat department? 5. Is straightening required and if so is this the responsibility of the heat treat department? 6.

DAY 3 Session 6 Gear Finishing: Lapping, Honing, and Grinding (2 hours) Presenter: Chuck Shultz 1. If the gear teeth or splines are to be lapped, honed, shaved or ground, this can typically be determined by the blueprint. 2. If the blueprint does not specify, general guidelines will be given as to when to lap, hone, shave, or grind. 3. The gear finishing will determine the type of machine tools required. 4. Indicate locating surfaces and tooling required to maintain gear tooth tolerances. 5. Tolerances to be maintained are typically listed on the blueprint. 6. Cautions regarding surface tempering, re hardening, and cracks. 7. Can cracks be present without the presence of surface tempering? 8. The blueprint should specify the gear tolerances, and if not, there should be a quality level such as an AGMA number. 9. In some instances operational sketches are provided specifying the tooth tolerances. 10. The importance close tolerance locating (chucking) surfaces and work holding tooling to control runout and accumulated spacing error. 11. The effect of excessive runout and/or accumulated runout when the gear is in the gearbox. 12. How runout can cause excessive stock removal in areas of the gear causing the depth of case hardness to go under minimal tolerances 13. Run out can cause surface tempering and cracks 14. The increasing demand for shot peening and its advantage for life cycle increase. 15. Time Permitting: A brief explanation of the following: Pin size or backlash Involute profile or V&H (EPG) Parallel axis gearing lead error and/or crowning Surface finish Tooth Spacing Hole depth Radius (A handout will be provided in the training manual showing examples of the above.) 16.
