My First Router

I never in a million years thought my wood router would cut this with no problems.
This is really opening my options up.
The renishaw probe made this uneven rock a boon to draw and cut.

Here is rock number 2

It's still wet so not too much contrast yet.
Kong this was done at a feedrate of 1000mm/min,it would probably do 4 times this but i can't nip my bum cheeks any tighter if you get my drift!!!!.

Just another view to show the contour of this thing.

Mark,
ok how are you getting the router to follow the contour of the stone? I am wanting to do something like that but am having trouble figuring out how to get the router to compensate for the varience in the surface. Thanks Ron

I probe the surface of the rock first and read it into my cad cam system then project the toolpaths on to it.Then post back out to mach2 and machine.Mach2 makes a superb job of probing and machining,But i think it screwed my router bearings.
Maybe just Crap bearings.I will check tomorrow.

Mark,

What are you milling the stone with? Wet?
I tried engraving a piece of granite tile. I put water on it and it still lit up my carbide cutter. It was just an experiment though. I guess diamond cutters are the only way.

Thanks,
Chris

The stone was just wet off washing,It was cut dry with carbide with no problems.The cutter was just a 6mm shank with a 4 sided point ground on it (like a pyramid).

Hi Fellas

Just getting back to my machine after months of other problems.I am going to build a congreve clock on the machine next See link for example.(http://www.williamcongreve.com/).
Thought i would maybe cut all the parts in one go ie,place sheets of brass on table 1/16" thick,3/32" thick etc.
Although the turned parts would have to be done on the planned cnc lathe.
Just tried a bit aluminium 1/16" thick and cut an example , it worked a treat.
I was thinking of maybe serializing my efforts on the zone if admin would maybe tell me where or which section/forum.
I need to get some serious cnc'ing done i think i got withdrawal symptoms.

Good to have you back Mark, I am sure the boss would love it if you would write it in the form of an article, which could then be posted in the articles section somehow! There was a post a little while ago asking for articles, but I lost track of where it is

[ger21]

How'd you hold that thing down to cut it?

[rmtucker]

Ger

I cut the inside first by clampng around outside then milled around the outside and left snap offs (Bridges) in 4 places about .004" thick so the job did not fall out.Then when complete you just press the job out of the plate.

here you go

Well i am taking the plunge and designing my own website around my homebuilt cnc router and my clockmaking projects.This is going to take up an awful lot of my time so i will be looking at the amount of visitors to my site and any feedback to see how far i should take this thing.

http://website.lineone.net/~rmtucker/

I am also hoping to update and give better descriptions of the building of the cnc to help some of the newbies out there.

Cnc Zone has been a source of invaluable help and encouragement to me and would like to thank all who answered and put up with my dumb questions.

I would say that i have finished the Cnc except for an operator panel and handwheel.

Please Remember that the website is under construction and will be changing on a daily basis so your patiance would be appreciated.

Once again thanks to all and i will still be lurking around the cnc zone every day.

Regards
Mark

Looks good, and I would like to see more about the Congreve clock you have shown. The history page just displays the word "History." :-) Of course, I'm a clock nut.

It looks like a very good beginning to a very good site.

Say, how did you engrave that rock? Did you design a toolpath to follow its contours? It looks like you followed the surface down the "step."

Mark,
I am also quite interested in your clock. I knew about Congreve's rockets because you launched them against us nearly 200 years ago :-) but didn't know he invented a clock. I looked up his clock, and it is a most interesting design. I had never heard of a rolling ball clock before. It must be interesting to watch one in operation. I will eagerly watch your progress on your web site.

Hi guys

I have found a use for my cnc router at last,Go to my web page at:-
www.weardalecnccarving.co.uk
in the march and april sections of the vwtrike build.

It may not look much at the moment but when i start on the engraving,the yokes and anything else i can fit on the machine will be covered.
It May give someone some ideas.

Regards
Mark
