that works .
thanks

so going a bit crazy trying to figure this out. i made a sheet with drawing template that i use 99% of the time. set scale 1:1 and 3rd angle. then i save the sheet format. everything is fine except...

running x2

thanks

long story short i toolpathed my part from the bottom.
my wcs is bottom and my t plane is bottom.
is there a quick way to change to wcs top t plane top?
i already have this programmed and i'm...

my understanding of 2.5 axis machining is that you can only create an arc in 2 planes simultaneously. all the cnc machines i have used can cut x,y and z at the same time. but not arcs on 2 planes at...

hi guys, so i'm now using mastercam x2 after years of gibbscam and surfcam. i need some direction on how to deburr the inside of a hole on a radius. i need to use a round undercutting / lolipop...

i've broached 1/4" hex into steel a bit.
spot drill for a pretty chamfer, drill just under the flats of the id hex,
undercut with a key cutter so you dont have that ugly mess at the bottom,...

i've done quite a bit of deep pocketing with small cutters. 3-4 cutters in decreasing diameters work well.
drilling the corners out with .005 clearance to the finished size helps

if they are like dice, i would skim/machine the top,do the outside and cut off with a saw cutter in the 1st op.the 4 outsides would then only need what you are machining into them. then for the saw...

sounds like you need someone with a broaching machine.
we used to do some in house, but i think we got rid of the machine.
not sure what the travel is on the broaching machines though.
this would...

actually, this won't work for thread forming. regular tapping yes, but thread forming has a bigger minor diameter and a tighter tolerance for the hole size.

here is how to figure out thread form...

i might be wrong, but from what i see, Mastercam is the one to use.not from any other perspective except most of the jobs i see ask for mastercam experience. i haven't used Camworks, but i do use...

[QUOTE][/G02 is for O.D. G03 is for I.D.QUOTE]

only if you are climb milling.
you can use either g02 or g03, but 1 way will be conventional mill.

for a circle, i would go this way with no cutter comp, 1/2" endmill,5" diameter.
x0 y0 is the center of the circle

g0x-2.75y-3.25(enough to be off the part)
g01z-____f_____
g01y0
g02I2.75...

not me.:D
i think programming from center is easiest.

personnally, i like to program from center when possible. it just makes things easier imho.
so say x0 y0 is the center of the part
no cutter comp, 1/2 endmill

g0 g90 x-2.75y-3.
g01z__f___...

do the tools drop only when you try to tool change after a heavy load?
a quick check would be to mill with a heavy load, zero return the z axis, then have an m0(optional stop) before the tool...

you can get a carbide circuit board drill in that size with an 1/8" shank.
.500 flute. they are about $20 each at msc.

I've been using a 5/8 corner rounding router bit on a certain part for a few years now. works great. it's carbide tipped and cost about $20. i believe a similar hss cutter was about $100.
i do the...

personnally, i wouldn't use a hollow mill or any boring head on this part. you have more to worry about with a mismatch between the sections of the bosses. i would finish it with 1 tool. that way,...

I would also go the 2 op route. but i would finish the outside of the long boss on the first op. i would also program the 2nd op boss radius a little bigger than the first side. you'll have less...

i have had great luck roughing aluminum with an abtools shear hog. its a 2 flute insertable shell mill. if Ø1.250 fits your needs, i would look into one.
i typically take .100 depth of cut, full...

you can put in user defined start points for rough mill, not finish contour as far as i know.
what i do is figure the difference between the radius i'm cutting and the diameter of the tool and put...

a bit off topic, but you don't really need helical interpolation to mill an npt thread. just cut the thread into 4 90 degree arcs and adjust the radius for the taper.

notepad is free and great for making g code.
this looks like a simple 2d part. shouln't take more than 20 minutes to program by hand.
helpful hint of the day.
if the part is symetrical, call x0...

seeing the limits of your machine, i would say to try drilling the corners out first. at 65 ipm this would take less time than slowing down the endmill in the corners.

don't forget to balance holders running that high of an rpm.
recommended balancing is over 15,000 rpm, but definately over 20,000 or you are going to have spindle issues.
and don't just buy...

we started at #1. every part has a different #.
there is also another # associated with the job for each po.
works great. all the routing info has the number on it.

for milling, g02 is clockwise, g03 is counter-clockwise.
if this an inside circle, starting from 9:00 it would be
x-.500y0
g03 i.500.
this is climb milling

to conventional mill
x-.500y0...

depends on the material, insert and coating. turning steels with a tialn coated insert and coolant can introduce thermal fracturing of the coating.
kind of like throwing boiling water on a block of...
