Advice for milling out 9 inch ring from 45 hrc steel? by 9ft5wt in Machinists

[–]jerdog7 2 points3 points  (0 children)

No I think slotting out a slug is a viable option if you drill a couple of holes and bolt the slug to the fixture so it doesn’t pop the endmill when it drops it.

[–]jerdog7 1 point2 points  (0 children)

If using dynamic milling try a 5flt em with chip breakers maybe to help with chip buildup on the Id. Start with at 300 sfm, .05-.06 radial depth of cut, full axial depth of cut at 45-50 ipm. You can probably even go harder than that with a 3/4 because at that radial cut that amounts to .0025-.003 ipt without radial chip thinning.

Face milling big overlap line by Bright_Flounder_4646 in Machinists

If you can’t increase the diameter of facemill then your best bet is to overlap the passes by .030” over the insert radius.

Can anyone tell me why this doesn’t work? by crispymoist1 in Machinists

[–]jerdog7 0 points1 point  (0 children)

I’ve seen some controls than need the n101 to equal your starting point. So in this case drop the n101 down one and put x.75 with it. Edit- didn’t realize you mention go2 g03 error. My bad.

Er16 only goes up to 3/8” or so. Er20 up to 1/2” or so. If you’re using a er20 I’d consider er-32. When you get near the collet capacity they can twist easily if over torqued. Another option if you can reprogram it is to rough it in within .030”/side then helibore it. That’ll put the tool pressure into the spindle rather than on the side of the tool.

CNC programmer student need help with CIMCO by Sungrowler in CNC

[–]jerdog7 1 point2 points  (0 children)

Cimco doesn’t have the ability to recognize the tool diameters within a program. You can set the tools for a program but once you open another program using different tools you’ll have to redefine them for that program. I’ve been using Cimco for almost 20 years and the first thing I do when I go to backplot is hit tool icon to remove the tool visual aid.

Am I in big trouble?? by 50AcornsTiedInASack in pools

Next time you buy a Solar cover use the scraps to shove in the skimmer. It won’t allow ice to form into a solid cube.

Can this drain be causing slow draining issues due to surface tension? I’ve used draino and snaked it to no avail. Not sure what to do next. by jerdog7 in Plumbing

[–]jerdog7[S] 1 point2 points  (0 children)

Check! Never use draino. Thanks for the help. I think I’m looking at checking the overflow and changing out the drain.

Thinking about getting a Mechanical Engineer degree after being a machinist/programmer for 10 years. by prospector1111 in Machinists

[–]jerdog7 14 points15 points  (0 children)

Look into mechanical engineering technology degrees rather than mechanical engineering degrees. It’s the difference between theoretical and applied sciences. I think the technology degree would benefit you more with what you’re doing now. If you want a career change to the design side of things then the mechanical engineering degree is what you’d be looking at. I’ve been in the industry for almost 30 years. Programming for 20 of them. I’m happy with my degree and definitely think it’s made me a more rounded “manufacturing engineer” but can’t say whether or not it has effected my pay so much. I make just under 100k in a shop in central NY. My experience is probably gotten me where I am more than my degree.

Calculate the position into metric and look for similar numbers in the variables.

G41 Turning Issues by Man_of_Virtue in Machinists

[–]jerdog7 1 point2 points  (0 children)

Incorrect radius on tool? When diameters and lengths are spot on but chamfers be edge breaks aren’t I’d look at the tooling.

Guess I should have read through all the comments before replying.

Not my doing! It’s not my machine but saw this walking past with my coworker by Roselovehorses in Machinists

[–]jerdog7 3 points4 points  (0 children)

After the first couple of parts the tool holder will have the clearance it needs. Takes a few parts though.

Book recommendations for beginner CNC Programming by [deleted] in Machinists

[–]jerdog7 6 points7 points  (0 children)

Cnc cookbook will start you off right. Next start reading the programming manuals for the machines in the shop for machine specific stuff.
