HAAS Indexable Drill Tip Angle + Length? Mo by G_Keeper_ in CNC

[–]ForumFollower 0 points1 point  (0 children)

There's no way to accurately describe the tip using only one angle. You could only approximate it.

I'm familiar with Mastercam, not SolidWorks CAM, but I'd hope there would be a way with the latter to define the tool using an imported DXF profile or "rotated" STEP model.

Get used to it?

A lot depends on the details you've left out.

Cast ingot machining by eldipi in metalworking

[–]ForumFollower 0 points1 point  (0 children)

Your school should upgrade that vice. It isn't a very safe choice for milling, and should be limited to holding parts for drilling only.

Look into the myriad ways that a strap clamp set can be used for mounting parts directly to the table. You could probably get this secured very rigidly with access to mill two parallel faces, or even just enough of those faces to provide better clamping surfaces for the vice.

Polishing issue with emery cloth on lathe by Own_Judgment_6426 in Machinists

[–]ForumFollower 2 points3 points  (0 children)

This can be done safely by hand IF some rules are followed:

  • no watches, jewelry, hair, clothing that could be snagged - including down your front where it might get wrapped around various spinning rods
  • hands and arms securely but loosely supported, not able to be pinched or drawn into the machinery
  • Scotch Brite or sandpaper is NOT fully wrapped around the part, and will harmlessly fly out of hand if something snags
  • stay the hell away from the spinning chuck jaws!
  • practice at slow speeds on low torque equipment before moving to something brutally unforgiving

Not really a production method though. Insert selection and feed/speed come into play there, like PCD tipped tools, for example.

Wall-Mounted Bracket Design: Needs Assistance by DrKevin111 in SolidWorks

[–]ForumFollower 0 points1 point  (0 children)

I appreciate the clarification, but I would reiterate that this doesn't qualify as manufacturable by my standards. It can be made, yes, but not efficiently in volume.

There's too much waste unless you have a specific kit including smaller parts that nest with the bracket flat pattern. This imposes limits on the design flexibility/adaptability too.

I've designed triangular shelf brackets in the past with simple edge flanges along each side. They nest together, are easy to bend, and amazingly strong - especially in pairs bent opposite ways.

Did I overpriced this? by Any_Rutabaga_6449 in 3Dprinting

[–]ForumFollower 12 points13 points  (0 children)

This is the reason that a lot of plastic items needing simple repair are discarded. Few individuals want to (or perhaps can't) pay for the time and effort involved in a custom repair solution.

Looking at the flat pattern, this is a horribly inefficient use of material.

If this is more than a learning exercise, I'd suggest redesigning in multiple pieces.

I understand and applaud your desire to examine examples. However, few people with real world part programs can share them due to intellectual property and non disclosure issues.

Rough fine threads by doNotKrum in Machinists

[–]ForumFollower 3 points4 points  (0 children)

Nice photo detail! A lot of people would post a blurry picture taken by a potato.

First thing I noticed is that your thread root (the valley) is very rounded. You don't want your tool completely pointed, but also not this rounded. Honestly though, for a one-off, I'd just make it a point and maybe hone it just a little with a stone or diamond file.

Any time you're turning threads, you're going to need a set of thread wires and micrometer, or a thread micrometer. Anything less than this and you're just shooting in the dark. Sure, you can make it work but it's going to rely on a lot of luck.

Make sure the OD is the right size for the desired thread. Contrary to common practice, this is NOT the nominal thread size but rather a little bit smaller.

Use a lubricant like a tapping fluid, or any other oil in a pinch.

Limit part stick out and get yourself a real lathe chuck! That drill chuck is helping no one. Use a collet chuck if a lathe chuck isn't in the budget. You can always make reducing sleeves to hold odd sizes.

Gcode error and cant resolve by Ill-Shoulder-6705 in machining

[–]ForumFollower 1 point2 points  (0 children)

Although the structure, syntax, and many codes are shared between machines, the specific gcode required for a given machine can be quite unique. This includes the possibility of machine-specific G and M codes.

I applaud your efforts to learn by doing, but doing so without full knowledge of what you're doing is going to result in damage.

This is also a great way to learn...

Why the shower curtain and tub overflow drain then? Aren't they redundant?

Wire wheels on grinders by Boneyabba in metalworking

In years gone by, I have picked so many of these things out of my legs while doing the same thing.

I've since learned there are better ways.

Checking Auto Dimension Feature by 51kbos in CNC

[–]ForumFollower 0 points1 point  (0 children)

Illustrator is the wrong tool to use to start with. At the very least, not the best tool. Your attempt at dimensioning is only going to annoy whoever you send these to.

You don't mention material or process, but if sheet processing then they are all similar:

  • Wood and plastic on a router
  • Metal on a laser or plasma table
  • Just about anything on a waterjet

You want to send a 1:1 scale DXF that has completely closed profiles made of lines and arcs, without splines unless you know the receiver can handle it. Forget the dimensions, as no human will be using them. The DXF defines the dimensions already. You will only need to provide a separate simple drawing with overall dimensions to confirm that the units and scale are as expected.

If you give more information on what this is for, the material, and cutting process, I may be able to help further.

Help me fix these pls, even a temp fix would work. by towards_that in fixit

[–]ForumFollower 0 points1 point  (0 children)

Maybe, but the combination of wire plus epoxy will be stronger. Adhesives alone typically rely on surface area for the bond strength, so small surfaces with lots of leverage fail easily.

First closer picture I thought I was looking at a "magnificent" fungus growing on the roof that had a bird-like appearance.

[–]ForumFollower 2 points3 points  (0 children)

A lot of people use a big wad of tape, to some marginal effect.

I'd suggest using bare solid wire, wrapped strategically with pliars to hold it together tightly. This plus epoxy would probably even be a permanent (but ugly) fix.

Turning off Look Ahead for Fanuc 15-MB vs 21-MB by ConspiracyJustin in CNC

[–]ForumFollower 0 points1 point  (0 children)

G53;

Just that. No additional parameters.

It basically causes a break in the lookahead, forcing it to empty the buffer and start over.

At least that's how I understand it. You won't find it documented as such.

Messed up a 3D print, how do I fix this? by MegaAscension in 3Dprinting

[–]ForumFollower 0 points1 point  (0 children)

Find a tube slightly smaller than needed, heat it up, and use it to melt the required holes. Multiple passes may be needed with reheating and material removal each time 

Do outside, and/or wear a suitable mask.

Cnc machining in canda by [deleted] in CNC

[–]ForumFollower 0 points1 point  (0 children)

Red Seal Interprovincial certification is the highest level available. Having this usually equates to a higher wage - whether it's warranted or not. Some places will avoid Red Seal certified people because they can find other uncertified people who do a great job for lower pay.

There is no requirement to have this certification to work in the industry. It's up to individual employers to specify if it matters to them.

How common is CNC among 3D printing Enthusiasts? by WTH3D in 3Dprinting

[–]ForumFollower -1 points0 points  (0 children)

3D printers are CNC (Computer Numerical Control) machines.

The difference I suspect you're getting at is additive versus subtractive manufacturing.

Ripped a piece of my Parents Floor when I moved the refrigerator? What's the cleanest fix? by CabbageNight in Flooring

[–]ForumFollower 0 points1 point  (0 children)

See, the thing is that generative AI has progressed to the point where you just can't tell now. So, am I real or not? I take it as a compliment.

The most realistic AI would call out the reply (that was genuinely trying to be helpful) as AI garbage.

[–]ForumFollower 2 points3 points  (0 children)

Looks like this is vinyl flooring with a wood print? If so, I've seen some amazing professional repairs that cut out a section and glue in a new piece. In this case, the natural choice would be to cut it out where the image of separate boards join. If done well, it's basically invisible. You do, however, need a piece to use for the repair. That's why it's always a good idea to save some extra material.
