Video - Prototype Handle

[wrustle]

Well as promised, here's the video to go along with the prototype handle pics in my other thread.

This video shows the handle being machined in our Haas VF0.

This was filmed during the first run, first unproven program, so it is slow going for safety sake, but hopefully you will enjoy watching it nonetheless!

Here's the link.........

Hi Russ - thanks for posting. I have a couple of quick questions:

1. How much faster would the machining time be once you know the program is good?

2. How is the handle separated from the remnant of the block?

I wouldn't know exactly how much faster, but I do know the cuts with the face mill would be faster.

The feeds for those cuts mentioned above were running at 50 IPM. If these ever go to production I would start them out at 75 and work up. Also the lead in would be minimized to just off the stock and would be a rapid rather than a feed. I would expect to nearly cut the time in half.

To separate the holding stock, I simply flip the part over and locate the "octagon like" shaped surface on parallels and hold the flat front and back face of that shape in the vise and face mill off the stock. I have a side stop locating off one of the tangs to find center so I can corner round the ends of the tangs and chamfer mill the top surface complete.

Best Regards,
Russ

Nice Russ,
Great fun to watch
Is that a "special tool" that looks like a hand and gives it a bit of a blow.

Thanks Russ - if they decide to go with that particular handle, it would be nice to see a video of the part being made to see the difference in time.

When he gets his new machine in his new shop, and I go beat on him to speed things up, that part will be done in under 1 minute. ;)

I'm gonna hold you to that statement!!

Heh heh....

I see it as actually possible if you go ahead and get at least a 12000rpm spindle with coolant thru, use a solid carbide coolant fed drill that cuts right to final size, and use a solid cabide coolant fed 3-flute end mill (made specifically for aluminum). That would be just 4 tools to complete the first operation; end mill, drill, groove, chamfer.

Ken - I guess it also depend if Russ charges by the hour or by the effort

Thankfully.......it's by the hour!!
