The meeting was held at Tom Davis' shop in South Tempe.
We started off with a Tour Tom Davis' small shop. Tom then demonstrated his machinery lift. We all trouped in to the TV and watched the first part of the CutterMaster video about sharpening end mills. While we got some good information from the video, we all agreed the production quality was really bad! The next step was to head out to the shop and try the machine out for real.
We start off with a box full of victims, er, dull end mills.
Tom points out the collet in the end of the air bearing ram that will hold the end mill
Tom sets the guide pin position so the sides of the end mill flutes can be sharpened.
Tom is pointing out the end mill to cutter wheel alignment
Another shot of the alignment pin
Tom grinding the side flutes of the end mill. Watching carefully (L - R) are Doug Endrud, Neil Peters, Doug Ramerth, Owen Jeffers, Bob Sanders and Gene Lucas' glasses.
Doug Ramerth takes a turn with the grinder, while (L to R) Jerry Carter, Tom Davis and Neil Peters look on.
Doug Ramerth discusses the results of the grinding process with tom Davis
Here we see the end mill being drawn across the cutting wheel. The tubular ram rides on a air gap provided with compressed air. If disturbed the ram will glide back and forth until it comes to rest. The movement of the bearing is incredibly smooth and the lightest touch is all it takes to move it. The end mill is aligned to the cutter wheel by resting the flutes on the guide pin. As the air bearing ram is pulled the guide pin rotates the end mill to keep the flute aligned with the cutter wheel.
Jerry Carter and Doug Ramerth are shown grinding an end mill.
Close up of the end flutes of the end mill being cut, note the low amount of sparking showing a light even cut.
Jerry Hine (facing left) brought a couple of very large drawings of a Pratt & Whitney R4360 radial engine. Are those doughnuts in that red box??
Here's the usual gang doing the usual thing at the end of a meeting, socializing and discussing various projects and machines.
There were some freebies exchanged after the meeting.
