We have a need to setup a prototyping shop to support an engineering department.

Production cnc department doesn't like prototype work because setups take a long time and take up highly productive machines. Their workflows are tailored to high production and excellent accountability.

Work envelope needed is generally up to 3"diameter but generally perhaps 1.5". Parts are 1/4" long to perhaps 12 or 18"depending. All materials including stainless, ferrous, non ferrous, and plastics. Quantity is 1-20pcs. Many parts need both turning and milling.

Thought 1: turn mill machines like Integrex. Why? Offline tool setup, lots of tools in the mag, good milling flexibility at any angle with a real mi

I love these cookies but they're super expensive. Anyone got a recipe that produces a similar result?

The cookies must be full of some kind of fat. Perhaps butter or shortening? A fair bit of salt too. They tend to stay pretty compact, and don't flatten out too much.

Sorry if this isn't allowed. There's really no sub where a question like this would get much traction. Robot will certainly be PLC integrated and that factors into our decision.

Question

Are 2002-2008 model year ABB IRB 1400/2400 robots with S4C, S4C+, or IRC5 controls reasonable accessible for people without years of robot experience?

Application

We want to load a CNC mill with parts (one at a time) for over night unattended operation. Overnight machining is not an issue for us, we do this for a fleet of CNC lathes with bar loaders/feeders.

Parts will sit in a magazine of some sort outside the machine. They do not stack so we need to have separate magazine positions for each pa

Marris otter base, with honey malt and lactose to make it a breakfast beer. Selected BRY-97 for its slightly higher temp range (house is generally 72-74°), better flocculation, and desirable ester profile (peach) for this particular silly beer.

Brewed and pitched on Sunday. A week later I've seen no airlock activity (6 liter, 1.5gal batch) so i wanted to test gravity. Using a white fermenting bucket so hard to see what's going on in there.

Started 1.056, a week in and we're at 1.014 and the krausen is still on top so i presume it'll get further down. Even 34/70 went faster than this, and faster yeasts finish in 36hrs generally.

Tastes really good at this point, obviously needs cleaning bu

We're thinking of picking up a 1998 okuma horizontal MX-40HA mill. With an OSP700L B control. 12krpm, .001 indexing. I need to check with okuma to see what options are turned on in the control.

We'll be running high production on aluminum parts. No 3d contouring, just 2d paths, drilling, tapping. Low part variety (3 parts currently). Simi-unattended production (4hrs per day after the first shift).

Anyone have experience with these machines? I've never run an okuma mostly fanuc but I'm fine to learn a new control.

Making a 1.8x0.95" pocket, 1.8"deep in solid aluminum.

Right now drilling 3x.75 holes to clear out material, then going in with a 1/2" 2flute 45° high helix 2fl end mill at 6000rpm and 40ipm around the perimeter, perhaps 0.4"deep per pas.

Machine is a nice fast rigid vertical Matsuura. 8krpm Max, i think it's 7.5hp. Flood coolant (not through spindle). End mill is held in a milling chuck.

Wondering if this is the most efficient way to cut this pocket. Anyone have other ideas on how to reduce cycle time?

I've made several 1.5gal batches during covid. They've all been drinkable but not necessarily something I'd pay for.

I'm wondering if anyone can suggest an easy yeast for an all grain batch on the light and dry aside for an apartment that is often about 72°f during the day.

Looking for dry, low ester, clean, good floccation. I will bottle condition. I've tried English ale, s-04, and 34/70 which have all been ok but still some off flavors. You could say I'm trying to make a light clean lager without the temp control.

Any suggestions for a simpleton like me?

We need to deburr hundreds of M5 holes in 20mm thick aluminum every day on a VMC. Both the front mouth of the hole, as well as the back of the hole (there's no other way to access the back of the hole).

Anyone use these Cogsdill Burraway units on a production basis? We need a pretty clean removal of the burr so that there is no little sharp edge remaining.

Heule has a similar tool but the tool body is $500 compared to $70, and the Heule inserts are $80 instead of Cogsdill $13. Anyone used the Heule to compare?

Any thoughts you have would be useful. I'm sure we'll just buy the Cogsdill unit to try, but if anyone has particular experience I'd love to hear thoughts.

We outsource several urethane elastomer parts to China. Typically 70-90 durometer, black. Quantity is typically 300-1000pcs per month of each part. They charge us about $1.50usd and the parts are about 20-50 grams each (I'd have to confirm this)

Does anyone have experience doing this molding in their shop? I see rim presses on alibaba. I'm a die maker myself or we could outsource the molds to China.

Looking to reduce costs and lead time. And provide more control over design changes and general quality. But maybe it's not economical after buying the machines and tools, given our low production. I don't even know where to get the raw materials or their cost.

I presume we need the press mach

I'll (Canadian) be a guest exhibitor in one of our customer's booths for 4 days. I've been told that in previous years, their lower-level people make liberal use of "gay", "fag" and "faggot" in normal conversation. You know the drill.

These guys are from several states around the US.

Should I make any attempt to either make my situation known (having a husband) or should I keep my yapper closed? We are certainly their guests and they have brought us in at considerable cost. It's also an important relationship for the company that I cannot jeopardize.

I certainly don't want to have a hardon about this and start chirping at anyone. This is not a political stand. I just don't enjoy listenin

Need to drill a hole approx Ø0.75-Ø0.80" to a depth of about 3.5" in delrin/acetal. Production job, 2,000 holes per month.

​

Currently using a long regular high quality jobber drill. But the geometry isn't great for higher feeds and good chip clearing. We do not have high pressure coolant. Current numbers are about 500rpm and 0.005"/rev feed with 0.25" pecks. Chips tend to melt at the bottom of the hole.

​

Anyone have good solutions for a drill that can eject chips well with a reasonably high feed?

​

I was thinking something like a spade drill but better quality than woodworking spade, and not as crazy expensive as steel-cutting indexable spade drills.

My google-foo is failing me.

I just had my car's rear right vent glass broken for the second time in two months. I'm reasonably handy but for the life of me I cannot find a supplier for a rear vent glass panel for my Hyundai.

I can get it done for about $200 (parts and labour), but I'd rather save $100 in labour and do it myself if possible. This seems to be a trend.

Anyone have any thoughts on where I can get glass panels in the GTA?

This is a tough shrine in the DLC.

I kept getting stuck at the last spike block, before the monk. Couldn't climb it, died many times there.

Turns out switching to the climbing set solved the issue. Climbed it the first time i tried with the set. Was wearing the ancient armour before and link would not get on the dang thing.

Hope this helps someone.
