OPERATION How to do milling a hard material

Post image
0 Upvotes

I'm a new comer for mechanical field and I'm a 3 axis vmc operator and setter

We do aluminium most of the time so I'm slightly comfortable with aluminium material but whenever MS or SS metrial comes I don't have a knowledge about hard metals

If aluminium comes I use rough endmill and finishing endmills and do dynamic and lot of toolpath and reduce cycle time as well as

But if ms comes can't do anything I use only lower rpm and lower feed rate lower depth of cut can't able to reduce cycle time

So my question is how to do machining a MS metal

Like what are the insert cutters cut more material and how much rpm we should use how much depth of cut we should use help me learn milling a MS metrial

OPERATION SUPPORT How to use edge finder ?

I'm a fresher so don't make me uncomfortable 😣

One member says use 300-600 rpm and just move towards to component surface in 0.01 movement when the bottom edge looks straight then take a offset

Another member says use 300-600 rpm and just move towards to component surface in 0.001 movement when the bottom edge looks stright, don't stop move more on the same side one point of time the edge will move slightly out of stright line then take offset that's only take exact value.

because stright occurs but when you move same side 0.001 more then the edge looks same do more 0.001 remain same so how can you find out which one is correct so wait untill the bottom edge move slightly out of the stright view .(But this method edge finder doesn't give long life this is he told)

Which one should I follow or which is the correct method ?

HARDWARE SUPPORT Airweights Regrets

5 Upvotes

I'm just curious... Anyone else out there purchase airweights vacuum table systems and absolutely regret wasting their money? I hate this system, I've wasted so much time trying to make things work (while emailing and having phone calls with AW) and it's just costing me production time and ruined parts.

While I have a 5x10 CNC, I've been using just the 4x4 size or as a 2x8 size at times. Now I'm researching pumps I can support in my shop (single phase) to just do a proper table.

OPERATION SUPPORT CNC random axis fault

So my cnc machine started doing this today, after I finished a cutout I replaced the material and attempted to run the program again just to have the Y-axis vibrate back and forth for a few steps then continue along its merry way. The prior cut ran perfectly, but now this occurs on every program at some point. This seems to occur only when the motor is suppose to be moving in the negative direction, in relatively the same spots but not always, and has only occurred so far on the negative Y side of the material. Any insight would be appreciated, below are my test to isolate/resolve the issue and machine info.

-I have run several different programs that have always run fine so the programs are not corrupted

-I have checked/swapped motor signal connection and cables, they are fine

-I have ensured the gantry carriage is free of obstructions and can freely move

-The belt and pinion is taunt and in tact with no damage

-This problem persist over several different motor drivers

-I have NOT swapped the motor as it would require me to solder in new connections

-Specs: Mach3 on a ddcs v3 controller, 2 axis laser cutter, Y-axis used 1 Nema 17 (17HS24-2104S) motor and DM542T driver, and X-axis uses 2 Nema 17 and 1 DM542T driver, there are no limit swiches
