Sounds like increasing chip load is the next step to try once the coating and honed edge is applied.

ATS has a 6" Kurt 8 station Cluster Tower for sale 500 MM base. Used very little. Also have several new CAT 40 and 50 HPI tool holders still in package. Email for details [email protected]

The drill is not failing completely, and not when breaking through. It still drills, spindle load is good, tip does not look good.

The solid carbide would be pricey. If the point geometry is similar I would be concerned about the same wear problem.

I should have said I can e-mail a photo of what the wear on the drill is.

Dia. is .377" some holes are 13" deep through. Not sure of coolant pressure as I am not sure how to read the gauge. It is just standard, not high pressure. Chip evacuation is good. I am not sure to attach a photo but I can e-mail one. [email protected]

I am gun drilling on a horizontal using just the basic water soluble coolant. Material is H13 but the tool does not hold up too long. So just wondering if any one else is doing this. The reason for using a gun drill is the special size and the length that is needed. Standard long carbide drill does not seem to be available.

http://dapra.com/tech/index.html has some nice calculators for download.

When I found I could not use high feed with dynamic fixtures, I just started using regular fixture offsets creating a new plane for each angle but keeping the same zero position on the part. I always set the T-plane/C-plane to the first offset at the B0 rotation. That is the only offset I need to set at the machine. Then I use a macro that will write the new fixture offsets to any angle I choose, and as many as I choose. This way I can use the high feed at any rotation. This macro is for a Fanuc 16i control. Keep in mind that the exact center of the pallet must be know just as with dynamic offsets. Email if You would like more detail on this.

Here there is not much production at all, so programming is from part zero. I also use a macro for rotation position. Lets say "X", "Z" zero is a certain position at G54 and B0, and I want the same zero position on the part at B27.5° and use G55, I enter the first offset in the macro and the new offset to use with the destination angle and macro will calculate and enter the new values into the work offset. This works for any angle very well but the exact center of rotation of the table "X and Z" from the machine home position must be known. Setting up the macro will also depend on how the tool length and work "Z" is being set. (as in (+) or (-) tool length/work values.

Has anyone been using the built in Iscar database tools with the increased HEM factor selected?

I am looking for a better solution to what We are using for square shoulder insert endmills. We cut a lot of tool steel including some of the old Crucibal type steels, Cruwear, CPM. Right now using Sumitomo. The biggest problem is so much of the product is designed around a .375" fillet so that is the size tool (.75" dia) We have trouble with the most. So I am looking for input on what is working well for others. Thanks for the input.

Would You mind sharing Your X5 report?

I have a macro I use for a Fadal control. One could do something similar for others.

I like the calculators You can download from Dapra. They have them for flat, torid and ball endmills and compensate for chip thining.

I have a question on this topic. I use the ftp to transfer files from the network to the machine hard drive. But I cannot seems to remove the files from the hard drive. Is this by design or do I need to find a parameter to change to allow this to hapen. I would also like the operator to be able to access and open the hard drive files (from a pc) in an editor and be able to make changes and save the changes. I was told this is possible but am not able to do it. Thanks for any help.

We have installed Smart Skim a few years ago for recycling. Does a good job removing oils. http://www.smartskim.com/

It the first screen shot if the dotted is geomerty, you could use could use xform templete and copy to endpoints and delete the duplicates.

Let say there are several different size arcs at "Z" zero plane, or at least all on one plane. I want a .015" chamfer on each size. I want to just plunge a 45° tool. Is there a way to select all holes and use some type off inceremental function to create the chamfers? Regards.

I have read some postings of users have trouble with the Hybrid finishing. Are some of You using it sucsessfully? I have not tried it yet and was considering using on a one up mold. Thank for any comments.

If You do get this figured out, I would like to know about it. I was told it cannot be done.

After the G54 line You could try the G66 macro call, as G54P6 G66 P6 X,Y X,Y X,Y G67 This way the sub should be executed at every X,Y position. G67 cancels the command.

Is any one using the Iscar tools and the parameters that are supplied in Mastercam for the HEM? What are the results?

I imported operation from another X5 file but the toolholder used for holderchecking did not come along? Do the tools need to be saved in the new library format first and they the files saved before this will work?

Can I please get a copy of this report? [email protected]
