Making Dish

Post by rdevine »

Hi.

I am newish to VCarve Desktop. Ive been using it for about 6 months. However I have been doing just simple pockets and contours. I want to start expanding my talents to more complex creations. I want to try and make a simple dish with a rounded transition from the side wall to bottom. Example below.

Am I completely overthinking this and something like a simple round bit like one used for juice grooves on cutting boards will do the trick? Trying to get as much done on the CNC to avoid a ton of sanding. I have many bits at my disposal like round nose, up/down bits, etc.

Use a bowl bit or a bowl bit designed to be used in a CNC machine.

May take this approach myself.....excuse the down and dirty file...needs tweaking.

A bit for specifically this. Could it be that easy. Thanks guys.

I’ll also download that file and see how you are tackling it. Appreciate the help. Will keep you posted.

The image I provided was from a guy I follow. I know he made his dish from other software. A little too advanced for my skill set that I have now.

Use a bowl bit
What depth increments do you use on a bit like that?

What depth increments do you use on a bit like that?
Start with the pass depth at 50% of the cutting edge length.

Feeds and speeds would be similar to an end mill -- which is heavily dependent on you spindle and machine's capability.

Make sure the bit does NOT have a bearing on it.

I really like the shape of that tray. Here are 2 alternatives that I think come a little closer to the original shape. The first uses a 2-inch core box bit to cut the curve, which may be too big for your Shapeko to run. The second makes the exact same curve using a moulding toolpath with a 1/4" ballnose bit.

Aah....I think you're more correct Steve.
At 4'ish when I looked at the pic the 2 closest edges looked as if as they went deeper,
there was a flat that got wider.
Just zoomed on pic and yours is keeping more with the pic.

I messed around with the file you created, thanks for that. Are you able to ramp up from the bottom to the sides? Think this has better look than just a straight wall.

Steve,

The moulding version is spot on. Thank you! I am dissecting your work so I can fully understand your workflow. Im not quite sure I understand the moulding toolpath. If I wanted to adjust the height of the walls how can I adjust that toolpath to allow for that?

There are a lot of things going on with this tray, so adjusting the height of the sides is a balance between adjusting the shape of the rail and profile vectors for the sweep:

1. If you flatten the curve of the sides on the inside vector that is used as the rail for the moulding toolpath it will increase the height of the sides but not the corners
2. Changing the depth of the pocket and also the height (but not width) of the moulding profile vector changes the height a bit

Frankly I did some trial and error to come up with what I did. I came up with the curve by assuming a 2" core box bit, cutting .625" deep which will give you something less than 1" for the width of the curve. Then I created the rail for the sweep so that the corners would be approximately the width of the profile curve from the cutout vector, and then curved the sides of the rail so that the moulding toolpath would cut beyond the cutout vector. I played around with that curve until I had something I liked.

Thanks Steve. As I mentioned I am new to these types of cuts. I’ve been watching some YouTube videos to understand more how it uses the extrusions along the shapes/lines. Rather than just cutting out your file I want to understand how each component works and how I can easily tweak sections to get the adjustments I would need.

I greatly appreciate you taking the time and entertaining my questions.

Looking forward to posting my own finished product. My friend wanted some dishes for her end table. She wanted to purchase some junk from Target. Naturally my creative mind kicked in and told her I’ll make her something better and not to mention make something with better material. Gives me the opportunity to use more function of VCarve.

Michael Mezalick did a video on clipart manipulation in V-carve Pro. It would be a good idea to view it. Unfortunately I can't seem to find it.
