Hello
My turning center with a Fanuc 0T had a memory failure and lost some parameters. We have most of them on record, but can't get Work Coordinates (G54-G59) back. Our printed parameter list doesn't list several of the parameter numbers starting around 900, which is where I believe the options reside. Can anyone help?

Welcome to the Forum Dave! Yes its tough trying to learn all this stuff, but once you get the basic concepts its just like riding a bike. At times all you have to figure out how to inflate the tires, tighten a few nuts and try to keep all your hair in the process. I don't have much hair left, but can't complain other than it gets cold in the winter. :)

Kind of in the same boat as you but not anywhere close to retirement. I would be glad to be making $20 hr. I am lucky if I can even pay the bills for my business let alone draw a paycheck right now.

Hello,

It sounds like you're facing a couple of learning challenges-
1 - Basic CNC machine tool setup and operation
2 - Basic CNC programming

Where are you located? In the US ?

I ask because, if you'ld like to get up and running quickly, you might
consider some on-site specialty training. There would be a cost, but
the investment might offer returns.

The Internet certainly offers much information from many sources, some
at no cost. If you for instance Google CNC from the .edu domain you could
tap into information that pertains to courses that many schools offer on-line.

I'm also sure you can find some help from the manufacturer of the machine, or alternately some form of training resource (I'm one) that could work with you
on a Time/Material basis.

This is a thread bump.

Cutting Profiles with BobCAD-CAM

Profile cutting is so common almost any 2D part you machine requires this type of tool path. From finishing the wall of a pocket to cutting around the outside shape of a part, profiling is essential.
We offer 3 types of profile options that accommodate for different profiling needs. These options can be found under patterns of the Mill 2 Axis Wizard

Standard:
Our standard profile cuttings allow for a rough and finish tool, stock for finish, lead in / out options and step down in z. This is the most common profile cutting tool path.
Watch a video to learn more: http://screencast.com/t/uaoSCEa1e

Contour Ramping:
This option allows you to ramp the tool around any profile. Common uses are for helical milling & slot milling. You control the angle of cut or a step down distance.
Watch a video to learn more:http://screencast.com/t/PB7txTXU7RL

Side Roughing:
Allow you to walk the tool in to a profile. Works best where you have more stock to cut then the cutter can take on a single pass.
Watch a video to learn more: http://screencast.com/t/4TNtJHmvWXW


With all profile cutting features you have compensation options, Allowing BobCAD to offset for the cutter, or to call cutter comp (G41 G42). These compensation options allow for wear comp, cutter comp, and center line cutting.

Using our profile tool path you can cut slots, shoulders, letters, holes, filets, t slots, dove tails, form shapes and other common every day 2D milling features.


If you have any questions please let me know.

hey, i have a puma 200s lathe with a fanuc 18i controler, the lathe works fine but i cant start the spindle or sub spindle with the start button, the stop one works, but to start it i have to type in s*** m03 all the time, anyone know what this could be ?

hey ive been programming mills and lathes full time for 1 1/2 years now, used to be a programmer/operator for 2 years befor that, im working in a small shop in blainville, Quebec. we do alot of one-of-a-kind and nice pieces, almost all aluminuim lol

how do I disconnect the 4th axis On a mattursa 1000 with fanuc 11m controls.It alarms out when I phyicaly disconect

Hello nithyanandr,

The software version is Sinumerik 810D

Your help will be highly appreciated

Im contacting you on behalf of my boss. He has Haas VF2 and had spindle replaced 6 months ago. Well 2 days ago the alarm Spindle Motor Overheat came on. And when restarting it wont leave screen is there a way restart or remove alarm by way of fuse or breaker the problem has been handled it was oil pump. Or is the spindle no goodThanks for your assistence.

Prabhat Mishra Every word of his reply are lies.
Dear Sir, Sorry for not replying before as I haven't seen the notifications.
Dear Mr Stevo, First please check the profile of Mr Edward Jones, Thats a fake profile created by this same man Prabhat Mishra to clear his name. He has 3 posts at the same date and that is his joined date also. His english writing is same as Prabhat Mishra's.

I didn't ask for any products without the legal documents or anything. He told me that he didn't have those and that is the reason for the delay because he was trying to get the proper legal documents. I can prove that this man is a total fraud. I have our skype conversations and emails. I'll send it to you if necessary.

I also got a private message from Mr Sandeep (profilename: san) saying that this Prabhat Mishra has stolen money from him also. you can confirm that by looking to my message inbox.

I'll post it here,

"Hello Sir

I saw ur post regarding prabhat mishra. Even i have deposited 26,000 to him for a spindle amplifier. But till date no reply... If we can workout together and trap him we will be able to recover the money. I am located in bangalore and I have his residencial address too...
Please do give me a call at XXXXXXXXXX.

Sandeep"

I lost money and a lot if time, I'll never let this man again to steal from another person

Thank You Sir.

Alarm 5 on the spindle drive , you have poped the 3.2 amp fuse on the spindle pcb. Its a 3.2a S fuse Yellow charcters. Its small green fuse, if there blown, they show a white flag in the small window. These somtimes "pop" over time , just replace it with the same type of fuse. is located top middle of the pcb, 4 to five inches from the top.

By the way the lathe has not crashed.
Does anybody knows how to rotate the turret with the handle control to realign?
Any ideas? Hi I have a proceedure on how to set the turret home position on a Mori MSG 501 Control, its a FS 21 control. you would have to let me know your e-mail so I can scan it, and send it to you. Why not contact Mori-Seiki, I am sure they will fwd you a copy.

I'm all new to this field, I've been doing it for 3 months now. I am working in North Texas at Halsey Manufacturing little place up in Denton, TX. I am learning to operate & program CNC Mills. Any advice or useful references would be awesome. I'm sure I will start posting questions soon enough so get ready lol.

Thanks to all.

The print may have worn off the pages in my manual, and therefore I've missed the reference to this issue in recent times. I'm sure there are many, as I am, interested in what you might find. I'll look again also, but what Paul wants to do would be possible via an Interrupt Signal Called Macro.

I had posted this a while back and thought the problem would get better. Gun sales are still selling like crazy due to various reasons. All major gun manufactures are having major problems with getting parts from their suppliers. I know for a fact that the lower receiver below is made for 5 or 6 major well known gun manufacturers. There is about 4 to 5 I think that make this part. Well one of the major gun manufactures has had a major part on back order for 6 weeks.There is a rumor they may have to go oversees to get the production rate they need on gun parts. With all this talk about we need manufacturing jobs I am curious are the machines that take to builds these parts too expensive. They are even back ordering gun barrel's.

Hi All,
Following is my answer to a question asked in another Forum. I'm Posting it here for the benefit of those who frequent this Forum, and my be interested. This Macro program calculates the Centre X Y coordiantes, and the Radius of a circle, the circumference of which, passes through any three points.

The program is started, and each time the Operator Message prompts "MAN TOUCH", select Hand Wheel to make the touch. Once the touch is made, select Auto Mode and press Cycle Start to record the current X Y coordinates. The process of "MAN TOUCH" prompt, manual touch with Hand Wheel, and coordinate recording by pressing Cycle Start will repeat until all three points have been recorded. If the control has the infrastructure for Auto contact with a Probe, the High Speed Skip G31 will be used if the control is by Fanuc, and no Manual intervention will be required. In this case, the probe could be roughly positioned in the centre of the circle/arc to be measured, and a diameter roughly equal to the proposed circle/arc to be measured passed as an argument by the Macro Call block.
For example:
G65 P9081 D100.0 S2 (D100.0 being the rough diameter of the feature to be measured)

Post any questions you may have.

Regards,

Bill

The following is a conversion of a routine I wrote for a CAM software package. Accordingly, I haven't tested it on a machine as a User Macro program. However, I don't think I've made any mistakes so it should be right to go. Test it in fresh air first. Post back with result.

If you use it to set a Work Shift, you could pass the Work Shift number to set in the Macro Call block.
For example:
G65 P9081 S2
Where S value
1 = G54
2 = G55
3 = G56
4 = G57
5 = G58
6 = G59

Then in the macro
#[5201+[20*[#19]]]=#15 (X WORK SHIFT)
#[5202+[20*[#19]]]=#16 (Y WORK SHIFT)

Obviously the above two Macro statement go at the bottom of the following program after all calculations have been completed.

Regards,

Bill

2. Rapid or feed to X#15 Y#16

Being that is a safety issue I want to get it resolved right away. Thanks in advance.
Its very unusual for an Emergency Stop circuit not to work. Normally an E/Stop function is arranged in the following way.
1. The E/Stop button press is monitored in software for the purpose of reporting the condition to the operator. But Emergency Stop should not be controlled in Software.
2. The circuit is so wired that it removes power from critical components of the control and machine.
3. The Switch is Normally Closed, so that if a wire breaks, the circuit Fails Safe.

It is a very poorly designed circuit if it does not satisfy the above, and would leave the manufacturer open to litigation in the case of injury involving the machine.

The only way I can see that the Emergency Stop circuit would fail, is if the Switch itself does not break the circuit. Accordingly, check that the switch is functioning correctly.

I'm not sure of the arrangement of the HAAS machine, but frequently, there will be a brake on the Z servo motor to prevent the spindle dropping to the table when power is removed. Are you sure that the Emergency Stop is not working, or the brake (if one exists) on the Z axis in not working? It should be obvious if the E/Stop is working, as the control should report that condition.

Bill
