Routing Wood
« on: June 08, 2008, 07:28:29 AM »
This relief was routed in oak 2.5 mm deep using a 3 mm diameter single flute cutter. The width of the sign is 350 mm which is the maximum size I can handle with the X - Axis. Longer signs have to be mounted sideways ( Y - Axis ) and cut in stages. This is the nameplate for a 'Beach Hut', which is a very appropriate name, don't you think ?.

At first glance I thought you were making a time machine. Looks like a job well done.

Another plaque for Art's stairwell perhaps ?. Neptune and Gemme / Gemme and Neptune, well maybe not.

This plaque is approx 150 mm x 190 mm and was cut in teak to 7 mm maximum depth. The cutter was a 3 mm diameter ball nose running at 3000 rpm and with a feed rate of F300 it took approx. 3 hours to complete. (The finished plaque has been gloss varnished and it was difficult to get a reasonable picture because of the reflections.)

The image is called 'Gemme', and this can be downloaded from Martin De Roode's website at http://engraving.majosoft.com/html/perfect_pictures.html.

I have posted my G-Code for this project if anyone is interested in cutting this plaque themselves. (If you use a high speed spindle then the feed rates can be increased considerably but to avoid overloading the cutter, reduce the feed rate by 50% or so for the first cut then reset to the full rate for the remainder. The X and Y zero is dead centre of the blank and Z zero is with the cutter just touching the work).

Happy routing.

This is one of the sample tool paths from the 'Vectric Cut2D'. It makes a very nice job but there are so many unnecessary and time consuming Z moves on such a simple plaque that I really wonder how well it will cope with a complicated design.

Some more of the Vectric Cut2D samples, cut in MDF.

Nice work, folks. Tweakie, may I ask how large the "Rocket" plaque is and how long it took with the (what size) cutter? I'm interested since I'm thinking of purchasing that for myself.

Hi Budman68,

Size of MDF is 290 mm x 100 mm, size of 'Rocket' pocket is approx. 170 mm x 60 mm.
Cutter used was 3.5 mm diameter.
Total time taken for Rocket and Wheel approx. 2 .5 Hours. ( I use a low speed spindle ).

Wow, you weren't kidding, that is quite a bit of time for that size, indeed.

Thanks for the info -  :)

Hi Budman68,

Now that I have had more time to trial 'Cut2D' and to be fair to Vectric - I conclude that the excessive time to pocket the 'Rocket plaque' is mainly due to the feed rates and 'ramp plunge' rates set in the example as I am pretty sure that it was intended to be made in metal not MDF. Secondary is the high number of closed loop tool paths caused by Vectric's pocketing algorithm. I just increased the Mach3 feed rate to 200% and started cutting.

I would be very interested to hear what times others have for machining these examples.
