Tanks for the input guys. Eventually found the problem. An extra 50 was stored with the tool in the diameter in the tool library.

I kind of thought it was in control def also. But I changed it a few ways and it made no difference in my out put code. Still D68 instead of D18. So I then figured it must be done in the post. So I did a search of my post looking for all "50" to see where it might be adding 50 and I couldn't find a thing. Baffling

We have our first Hurco. I've got a generic Fanuc post I am trying to make work. Hurco is in ISNC mode thus able to read standard code. # 1 post change I need is for the code to output D18 in the program with the T18 tool when using comp. Currently is outputs D68 with T18. Can anyone tell me what I need to change in my post? Thank You

We had to pay $250 for a version of Cimco editor so a PC sitting next to a Mill could use it for file transferring. "note no hasp on this computer" So it is not free as a stand alone. When you install a new version of Mastercam it does come included and is one of 3 editor options you can select. Mastercam editor, Cimco Editor or Note pad

yes I to have the same issue. When it happens it will occur when I go to type a drafting note. I then have to force Mastercam to shut down in the task manager.

In regards to Spot drilling. This is really necessary for us. Because we are using long drills from start to finish. Unable to sacrifice another tool pod for pilot. Spot drill is keeping our position. Keep in mind our spot drill is 140 deg. Which is a greater angle then our Guhing drills. Thus when the drill makes contact with the material it is only cutting on the center and not the outer edges. CNCchipmaker I am really liking your macro suggestion. Although in my 25 years of machining I have never used or seen a macro in use. Kind of over my head how to test and implement this. Does this macro sample you wrote above get implemented into the post or is this Macro stored in the CNC control panel? Also would using something like this drastically increase the program size? Would for example drilling qty 400 21/64 holes be much more then just moving to X , Y position in a drill can cycle? We will try your Macro B test at the control soon. MDI #100=1 Thank You much

Thanks guys we do use Guhring drills. We only spot drill -.050 140 deg first to keep the drill centered well on position. We are Not spotting deep enough to chamfer the hole. We are using longer Guhring drills in order to get thru 3 inch die sets. Common carbide drill sizes we use are 13/64 , 17/64, 21/64, 23/64, 7/16, 31/64 and 17/32. We really can't sacrifice our 60 tool pod holder with duplicate drills. That being a short carbide drill for starting a hole and another tool pod holding a long carbide drill to get 3 inches plus deep. My goal is to continue using our longer drills from start to finish. But take it easy with the drill for the first 1 1/2 times dia depth that being no spindle thru coolant and slower speed and feed. Then accelerate thru once at 1 1/2 times deep, dwell for a brief moment to turn spindle thru coolant on, and increase speed and feed to normal. Perhaps what I am hoping for may not be possible. So I am certainly interested in hearing how others are drilling with carbide. Thanks again, Keep the comments coming. PS I should add our max spindle speed is 4000 rpm. So some of those smaller drills we cant drill per recommedations. But we are maintaining the chip load.

Mil -tfp-41 you have my curiosity with the points tool path. Never heard of this. Are you drawing points at different depths at a hole location or something? Unfortunately yes we are doing many holes, sometimes a die set may have qty 400 3/8-16 tapped holes for example. We are not apposed to having our post altered if what we want is possible. I am familiar with using a I,J,K in a G83 cycle to achieve a variable peck amount. But in addition to that we are wanting speed, feed and coolant type "spindle thru" to change in the middle of the drill cycle.

We been having trouble with tool life on our solid carbide drills “corners chipping”. Currently we turn spindle thru coolant on and push the drill thru with no pecking. The tool salesmen wants us to change our procedure. To something similar to this. Drill depth 1 ½ to 2X dia of drill with no spindle thru coolant but flood only and speed to be slower and feed to be slower. Once we reach the 1 ½ to 2X depth we want the spindle thru coolant on and speed and feed increase to normal. We believe the spindle thru coolant causes vibration at the drill point when starting a hole. Also wanting to start the drill at the material face less aggressively with less speed and feed. Is this possible to do? Is there a drill cycle that does something like this? What type of procedures are others using? We are drilling on a Johnford vertical machining center Fanuc control. Mild steel die sets often 3 inches thick. Also commonly 4140 and Tool steels anywhere from 1.250 to 3 inches. Yes we do spot drill first with a 140 deg carbide spotting drill. This 140 deg angle is larger then the drill point so the drill tip makes contact with the matl surface and not the drill edges. Appreciate any input. Thanks

Humm still thinking you may not be following my goal. I know you think so. sorry hard to explain without a pic. Not sure how it works but i tried to attach a .bmp to explain better. I did did dink around with your suggestion but no success. junk.bmp

I'm thinking your not maybe understanding my goal? The edges are all .125 it is where 3 edges intersect at the corner that i want rounded off to a .250 radius. So as an example if you extruded a 2 inch to make a solid 2 inch cube. Now created a .125 radius on all the corners. Your 3 corner intersection should be .125 also "unless you had mitered selected". Now the next step I want to do is make those 8 interesction points of the cube a .250 radius. Basically a round knob on all 8 corners of the cube that is .250R . The straight edges will remain .125R. I do appreicate the help.

I had actually already tried that. Doesn't give me what I want. You can't control the size of the radius it is adding.

No not quite what i am looking for. Wish I could add a picture to show. Imagine a square block with .125 radius all around the edges. But now you want to add a .250 Radius on the intersection corners only. Thanks
