General Mach Discussion / Re: VFD recommendation

« on: August 06, 2006, 05:27:49 AM »

Hi Hood,

not according to the drives warehouse web site, they list VFD's for both AC and DC motors.

General Mach Discussion / VFD recommendation

« on: August 05, 2006, 07:09:11 PM »

Hi All,

I am looking for A VFD unit to drive a .75HP DC motor. Any recommendations for use with Mach3.

Most CAM systems can do this, they call it 3D project or face wrapping, I use alphacam and it will do this no problem.

Sound as if you have 1 of 2 options

let visual mill re-post the code with new feeds or drop the code into notepad and do a search and replace of the a feeds.

What is the code like if you tell LZ that the cutter is .125" dia

I use a standard Fanuc 6 post on alphacam and it works fine.

What do you mean?

how do you want to reverse the axis, and under what condition?

Hi,

you can not have a rad that starts a Z0 and moves to Z-.5 when the radius is only .40625", its more than a 90 degree move.

If you want to go over 90 degrees you have to do it in two parts OD1 then OD2

You could do it with one sub program by changing the # values between the sub calls.

O1000

#1=-0.45 (Depth to go down in first phase)
#3=5 (Number of steps for first phase)
#5=0.180 (Y for first phase, considering 1/2 inch tool size)

G90 (Absolute distance mode)
G00 X... Y... Z.1
G01 Z0 F2.
M98 P1001 L#3 (Call phase-1 #3 times)
G4 P5.0
#1=-1.250 (Depth to go down in second phase)
#3=8 (Number of steps for second phase)
#5=0.030 (Y for second phase, considering 1/2 inch tool size)
M98 P1001 L#3 (Call phase-2 #3 times)
G1 Z0.0 F6.0 (End)
M2


O1001
G91
G1 Z[#1 / #3] F2.0 (Feed down)
G90
G1 X2.400 F6.0 (Go to the right)
G1 Y#5 F6.0 (Go away)
G1 X1.650 F6.0 (Mill away far side)
G1 Y0.0 F6.0 (Come to start)
G4 P5.0
M99
