Hypermesh - how to move and align your FEM with the Global Coordinate System
This video is aimed at FEM analysts using Hypermesh with Nastran and Optistruct solvers. Often a local model is created from CAD geometry that is orientated at random angles from the Basic or Global Coordinate system. This is not convenient for FEM validation or looking at the grid point force results file - which is always in the Global system. Therefore this video demonstrates how to move the model and align it with the global system making it easier to check/validate and understand the results.

Myford ML4 how to measure RPM and cutting speeds
Переглядів 6 тис.6 років тому
Recommended cutting speeds and why knowing them is important. Two methods are shown to find the RPM of a lathe spindle and chuck. A quick way using a cycle wheel and an accurate way using the lathe's back gears. How to convert RPM into linear cutting speeds in feet or metres per minute.
Myford ML4 lathe
Переглядів 12 тис.6 років тому
My working demonstration of my Myford metal turning lathe that has been in the family since my father bought it to make a single cylinder petrol engine for his cycle in the 1930's. My research suggests this to be an ML4 but if you disagree I would appreciate your comments.
Door Seal Nonlinear FE Analysis using Mentat

Gordon Mutten describes how to perform a Nonlinear finite element analysis of a rubber P-Seal using Marc and Mentat software
What oil should be use for the bearings
I have always used a good quality car engine oil as it has excellent corrosion resistance etc.
Hi, what oil should be use for the bearings?
Hi, I have always used a good quality car engine oil because it has excellent corrosion resistance etc
Hi , Would you be able to do a video on how to get oil to the counter shaft bearing please , also how to adjust them please
Hello there. I have a very similar lathe to your one. I am searching the internet for the gearbox for it as seen about 30 seconds into your video. I am in the west of Ireland and these old myford a are not common at all in this country, let alone this side of the country. Great video. Regards. Dannie.
sir, could you explain to me *comp 22 of stress* means please? thanks
danke schön
Sir, could you help me to draw solid cone or frustum in mentat
Sorry I'm unable to help you with that. I only have access to ALTAIR software these days.
@@engineeringstressintuition5083 No problem, thankyou sir
Like the cycle wheel idea, will try it on my ML7 tomorrow. Thank you.
I have just been given an ML4. Are you able to tell me if I can replace the original 3-jaw chuck with one for a ML7?
Possibly, but to be sure I would ask myford.co.uk
hi how can i move just one color part (like blue one) and the other not move
When your part is blue, it's in its own Component. When you select your elements, there is an Option by collector, here you can choose your desired Component.
Definitely an ML4 but not the earliest which did not have a cover for the change wheels and was driven by flat belts rather than vee belts.
Great tutorial, explained well enough that a layperson could understand.
A very useful video. Thank you
Looks like a 4 ive got a 3
Why not get a speedometer - with a wheel you push against your work and it'll read the ft/min directly for any diameter bar ! www.checkline.com/res/products/125806/mt-wheel.jpg
You can also download a strobe app for your phone
Thanks ! Not seen one of these before. Our first lathe was the ML7. It looks tatty but I don't mind tatty at all as long as it's well oiled. I'm disappointed if you no longer have it.
if you want the door to move with an angle of 30 degree for example, how can you do in Marc Mentat ?
Great video, thanks!
It is useful tutorial. Thanks for your VDO :)
It's an ML4 with upgrade to the tail stock. Long cross slide screw. Large diameter dials. With a threading dial, I’ve never seen one on a ML4.
I have one. It is titled as an ML4 Tumbler Reverse. I also have the thread dial indicator, which was bought in 1964 and cost £1. 2s Op.
Thanks for this video. I'm constantly searching for more footage/info about the ML4 as I recently inherited one.
great tutorial, thanks
HI, can you do the tutorial on the metal cutting operation?
Sorry, but I no longer have access to Mentat software.
Does anyone use Mentat in real life ? I've had a go at it and it's dreadful. Not in the slightest bit intuitive. I've used HyperMesh since 1996 and I've yet to find anything that beats it. As for MSC.Marc. Horrible. The deck is unreadable. It makes hand editing it very difficult. I found that Abaqus is very use friendly with Optistruct coming up to speed.
Oh brother tell me about it. This stupid program has absolutely no content over web no tutorial whatsoever. Only this man made a tutorial which is feasible. Other tutorials are straight out bullshit if there are any
Tanks
The best Tutorial of Marc Mentat on the entire Web. Congratulations :)
This lathe is now for sale from Cheltenham UK.
Engineering Stress Intuition If by any chance you still own this lathe, please would you contact me on msj dot beard at yahoo dot co dot uk?
I wish I had your lathe it would make for a good base model to restore. See here. www.lathes.co.uk/myford-ml2-rebuild/ Also info on the ML range you may find an interesting read. www.lathes.co.uk/myford-ml2-ml4/
It does look like an ML4, I'll measure my bed tommorrow, if you measure the bed where the saddle and tailstock is then this will give you confirmation. Yours has some nice refinements which make for a good usable lathe, firstly the clutch mechanism, so drive can be halted while the motor is still run, useful for the life of the motor. Also the forward/neutral/reverse on the leadscrew. A modification that I wish mine had. It also looks yo have the more advance tailstock design that was released by myford after many people complained about the lack of a proper settable tailstock design. Without hours of fiddly setup. This was offered as an optional upgrade at great expense, but delivered a much better tailstock that could maintain iys concentric setting longer than two seconds. Finally the guards to protect your fingers and clothes from been trapped in there. All in a decent package for an ML4. The only thing that I would upgrade on that one is to install a 2:1 gear and handle bolted to the apron which will mean that the saddle traverses the correct way when the handle is turned. Though if you have lived with it all your life then it would not feel so backward to you.
Thank you - that's really interesting. I do know that the original tailstock cracked and had to be replaced by my father in the 1960's so he must have changed it for the improved version then. I have always been used to the apron handle working the wrong way - but I never had a problem using other lathes that work the "right" way. The machined slider of the bed is 26" long.
Engineering Stress Intuition what's your bore on the spindle? There were two options offered for this also the standard MT1 socket 3/8" (upto 0.400"). Or the slightly larger MT2 socket spindle which I think cleared 5/8" materials. So called the big bore conversion.
it just clears a 15mm pipe - looks like it was bored to 0.6"
Engineering Stress Intuition big bore MT2 socket spindle then. It's got all the mod cons 😊
@@engineeringstressintuition5083 0·625 is 5/8" !
It's either an ML4 or an ML2 dependant on the bed length. What makes you think it's something different? My lathe is an ML4 and I can tell you for sure that it's one of the two, guess would be the 4 but without a measurement I can't say for certain.
The external length including the geartrain cover is a fraction under 38 inches.
Hello, I really enjoyed this video, I wish it was longer. I have recently bought this model as a ML4 and it looks very much like yours. Do you think you could post some more ML4 videos as I am new to this and am getting on in years, So I do need as much help as I can get. many thanks Colin.UK.
Thanks for your comment Colin. Is there anything in particular that would be useful to you?
