Webinars

Thank you for joining us today for a webinar on Advances in combined process machining or multifunctional machining.  In today’s webinar we will conduct a question and answer webinar explaining the latest Gleason technology in our combined process that will include Turning, Drilling, Milling and Hobbing all on one machine and one set up.  We will highlight technology Gleason has built into the machine to achieve these processes.

Today’s CONIFLEX manufacturing on CNC controlled Free-Form-Machines is not only the conversion of old fashion straight bevel gears from outdated mechanical machines to more recent equipment. CONIFLEX®Plus is a complete revitalization of straight bevel gears. For the calculation and optimization a newly developed software package was developed, which allows to generate theoretical flank forms which are used to conduct virtual tooth contact analysis to predict roll performance. This new software enables the user to develop, next to the common generated straight bevel gears also modern FORMATE designs. Now it is also possible to develop internal ring gears for special applications and Hirth style couplings. The new software generates nominal data for coordinate measurement and a new correction package delivers corrective settings in order to establish a closed loop manufacturing. The manufacturing process utilizes CONIFLEX®Plus stick blade cutter heads in a high speed, dry PowerCutting® environment. Cutting of straight bevel gears becomes with the new process very fast but also environmentally friendly. Surface finish, Flank form and spacing quality of the new CONIFLEX®Plus manufactured gears are superior to the straight bevel gears of the past. With a new CBN coated grinding wheel technology it is now also possible to grind straight bevel gears after the heat treatment. This opens the door to many new applications, where the advantages of straight bevel gears in combination with highest finish accuracy is desired. The Webinar on CONIFLEX covers the specifics of all new straight bevel developments; it shows examples gears and features several videos of the new, revolutionary manufacturing process.

Dr. Antoine Türich, Director Global Product Management Grinding Solutions, will provide an update on technology issues for Threaded Wheel Grinding that will cover dressing techniques, VRM Grinding to achieve quieter gear noise and our patented Anti Twist method.

The next Gleason Webinar is based on a paper that was written and presented by Thomas "Buzz" Maiuri at the AGMA Fall Technical Meeting. The title is "Hob Tool Life Technology Update". The abstract submitted to AGMA about the paper follows: The method of cutting teeth on a cylindrical gear by the hobbing process has been in existence since the late 1800's. Advances have been made over the years in both the machines and the cutting tools used in the process. This paper will examine hob tool life and the many variables that affect it. The paper will cover the state of the art cutting tool materials and coatings, hob tool design characteristics, process speeds and feeds, hob shifting strategies, wear characteristics, etc. The paper will also discuss the use of a common denominator method for evaluating hob tool life in terms of meters [or inches] per hob tooth as an alternative to tool life expressed in parts per sharpening. The Webinar Presentation Topics will include: • Brief History, Definition, Video of the Hobbing Process • Cutting Tool Materials and Coatings • Hob Wear Basics • Hob Wear Indicators • Hob Tool Design Recommendations • Tool Life Variables • Hob Life Measurement - Meters/Hob Tooth • Speeds and Feeds • Tool Wear Criteria • Hob Shifting Strategy • Wet and Dry Hobbing
