Use a trim boundary to cut the outer profile in one operation, then in a second operation change the trim boundary from outer to inner or vice versa to only cut the inner.

No the site is not wrong, it does not say that Conventional should be used for finishing definitively. But only when you are experiencing trouble with deflection.

In certain instances where you are having trouble with deflection, Conventional can be a better solution, but other than that Climb is definitely the way to go.

CNC Cookbook link - Climb Milling...

The reason that you are getting the line in the center of the groove is that even though the ballmill is centercutting, the cutting speed of a ballmill acts the same as a drill, i.e. it decreases as...

Sorry, my only interaction with sequential mill is that I have looked over the operation, which compared to all other types of operations, admittedly, left me thoroughly confused.
Its on my "to do"...

The path that you have on there requires 5-axis, the approach and departure both are at compound angles to each axis.

rdsnx's solution is the way to go if all you have is 4-axis capability, but...

Is there really a need for the S200 M3 before the tap cycle?

When we do rigid tapping the output is as follows, with just the M29 and spindle speed wanted? Maybe the two spindle commands are...

If you go to eng-tips.com on the Siemens/NX forum you will probably get a better response to your questions.

I agree with tc26, but something to get those chips out of there would definitely help. Coolant when cutting alum. is used as more of a lubricant than as an actual coolant so is not an absolute...

What kind of RPM's, Dia. of tool, stickout? It's awful optimistic trying to cut steel of any sort, never mind 304 stainless on a router! A general rule of thumb for 304 stainless is, Low Speed, High...

For what you want it would be around .500 - 1.00ipm depending on pressure available (ours are 90,000psi) and finish wanted.

We have waterjets and lasers, and for 1" thick materials I would go with waterjet out of the two choices, we cut titanium with the lasers and struggle to get them to efficiently cut anything over...

I would slow the RPM's down to around 300RPM's and keep the feedrate where it is which will up you to .002 per rev., there is probably some work hardening going on and that is most likely what is...

1/4 of the dia., not .250 DOC!! So, .125 for a .5 endmill.:cheers:

I was thinking more like 1/4dia DOC in the steel, but even at the .025 DOC I think 6-7ipm's is more like it. In the video it sounds like it is hammering away especially for that small of a cut. Also...

The Alum. F&S's look good for HSS, the Steel F&S's are fairly aggressive even for carbide in softer steel. What type of steel are we talking about here.

Can you post some sample code in the format that you are wanting so that I can see the difference.

What type of operation are you using? If Planar Mill, the boundary plane has to be set at the distance above the floor that you want for your top pass, if it is set to the same level as your floor...

For a plunging cut you need to slow down the IPM's those F&S's may work for milling but for plunging I would drop it down to around .3 IPM and increase to 2000 RPM. Maybe peck so that you can get...

Here's a screenshot of what G-Wizard says, set to conservative for a good finish. 6000rpms, 66ipm, 25% feedrate in corners.

Even with the carbide the deflection is still at about .0009 at the 3.25 stickout which a lot for a finishing pass. A depth of cut of between .100-.150 would drop it down to .0003

With the 1.00 tool it seems like you are having rigidity issues with either the machine or the setup. I would try smaller depth of cuts both axially and radially, start small maybe something like .05...

No you're calculations are correct. Those specs from your first post result in .8 HP requirement, where you are going wrong is that you are assuming your machine is 100% efficient. But if it is...

Lost productivity compared to your stalling the machine continuously, machine breaking down from pushing it too hard, and other costs associated such as broken tools, so how much productivity have...

True the stickout doesn't effect the power requirements but it does have a lot to do with getting the right Feeds & Speeds. The longer the stickout the more the deflection grows exponentially, and...

How much stickout? How many flutes? In Alum. you should be running 2 flutes, no more than 3 at most, especially when slotting. With the DOC's that you are running it is consuming between .5-1HP, try...

I have attached a screen shot of the G-Wizard Feeds & Speeds page set to the tool specs from your link, look it over and compare HP requirements and limitations, it is set to a very conservative...

A little more in depth desc. of tool, I'll plug it into G-Wizard for you. But just off hand I'd say .01 doc, 1900 rpms, 30-40 ipm.

You could also use a Fixed Contour op., use Surface Area drive method, select the inside wall surfaces, select Helical as the Cut Pattern, set Stepover to Scallop, and Vertical Limit to the preferred...

When you select a Cut Area it has to be included in Select Part. Either select the white sheet as a component of the Part if you need to stay up off of the actual part where it overhangs the actual...
