Thanks everyone for the input. Hopefully this will help light the fire to bring 5-axis in house.
-
John - you and I both know it can do it. My boss is looking for some opinions about the 5 axis module before he invests in another CAM package. I told him MCAM will be able to do it just fine and I would get real world users opinions about it.
-
I was asked by my boss to post here and ask what others (tool and mold programmers) think of Mastercam's Multi-Axis / 5-axis module. I guess we are looking into purchasing our first 5 axis this year. The salesman who he was talking to (I don't know what machine manufacturer) says Mastercam cannot do 5 axis and proceeded to start promoting Powermill. From you guys using the multi-axis / 5 axis module - how do you feel Mastercam performs in 5 axis for doing cores and cavities for plastic injection molds? All comments are welcome.

How many use check surfaces in HST toolpaths?
Brian B 74 replied to crazy^millman's topic in Industrial Forum
Boundaries and drive surfaces here. Didn't have much luck back in the V9 days so I have become accustomed to using custom solid models with faces offset in areas where I want to leave stock. -
I see there is no option for this in the toolpath, so, how does one go about doing a HST Horizontal restmill with a smaller cutter? Is it a matter of creating boundaries in the areas that need restmilling and just using another horizontal toolpath?
-
They don't post Cutter Comp from NX (post isn't setup to output correct code). It all comes from MCX.
-
Have 2 Roders here - 1 for graphite - 1 for hardmilling. 90% of the programming for them comes from Mastercam (other 10% from NX). I use cutter comp for finishing round and square pockets. It can be done but sometimes the control doesn't like the code (and for no reason). For such a high end machine it cannot comp a helix movement like a Fanuc - so no 2D contour RAMP or helix bore programs.

It's all good! I appreciate your help. Thanks!

Took some time to find that cimco.ini file but once I did I just copied all the directories over. Problem solved. Thanks for the help!
-
Morning all! We just had a new server installed yesterday and we all got new user names and passwords on a new domain. I had a backup copy of all my MCX settings so that wasn't an issue. HOWEVER, my Cimco editor (one that came with MCX) has now reverted back to default settings. Is there a way to copy Cimco settings from 1 user to another? My old user profile is still on my computer and can copy and paste from it. Thanks!

Where do you buy your Solid Carbide Endmills?
Brian B 74 replied to Jason @ CPM Industries's topic in Industrial Forum
Jason - You cannot go wrong with Fleetwood in Addison or Quality Tools and Abrasives in Elk Grove Village. We get our Garr endmills from Fleetwood because we cannot find anyone to beat their prices. We also use YG-1 and we order those from Quality Tools. Both carry many lines of carbide endmills (including Titan). -
Is there a way to get an OptiArea toolpath to start at a pre-defined point? I am roughing a pocket that I would like to put a start hole in for the OptiArea toolpath, but it seems like everytime I make a parameter change and regenterate the start position moves. I tried using the Approximate Start Point but it still moves around on me. Thanks!
-
Other nice thing about TNR - your program should match your print. On simple turning projects I preferred to use canned cycles. It allowed to make changes to the D.O.C. on the fly without having to re-post code. Most times I would just program a finish cycle and copy/paste in the canned cycle code.
-
I was getting a shoulder collision down in a deep pocket. I don't like describing custom tools to show a small shoulder diameter (relieved cutter). I got rid of the collision by turning on the tool path smoothing (had arcs already turned on). Thanks for the help John! It's greatly appreciated. BB

Is there a way to get an Opticore toolpath to do a finish pass on each level before stepping up to remove the cusps left behind? Or does it need to get done a different way? Thanks!
-
Hi All! Does anyone have some code I can borrow to develop a custom drill cycle for our Fanuc control? I am looking at using a drill 30xD (OSG Helios) and it says to drill a pilot hole about 2xD. On a low RPM get the Helios drill into the hole. Turn up the rpm to the recommended SFM and drill the hole. Then feed back up - slow the rpm and exit the hole. Can anyone help me with this? I was thinking maybe a Custom Macro, but MCX code would be best. Thanks!
-
Hasn't run yet. Maybe another week or 2.
-
I took the 1000SFM right from the Garr technical data. I also took their recommended .0015ipt and used that to calculate a WOC compensated feedrate (.0035ipt). I will plug your numbers and see what kind of cycle time I come up with.
-
Ok. Decided to go with a Garr 545RA 1/2dia R.06. 7650rpm 131ipm. .560doc .025woc. Stepping up wasn't showing a really good tool path so I left .030/s and switched to a waterline. Finished the rest of the part the same. Estimated Cycle time with Garr - 1hr 30 min. Estimated Cycle time with OSG High Feed - almost 3hr. I am going to risk it and try the Garr. I will post the results when available. BB

Has anyone had any success machining hardened H-13 using Opticore? I have a solid piece of hardened steel that I need to machine some core sub inserts from. In the past I have always used a OSG highfeed cutter taking a .008" DOC and .150" WOC going 250 IPM. On this particular block my roughing cycle is over 3hrs. I would like to try using Opticore with a Garr VRX bull mill and try to get a better cycle time. Is this feasible? Or am I better off with a high feed cutter? I am doing this in a Roeders RFM600. Thanks!

Mold Base Plate Machining
Brian B 74 replied to Brian B 74's topic in Machining, Tools, Cutting & Probing
Thanks for the feedback. I am heading to IMTS to look at work holding options. I found this but dunno if it is practical. http://www.fcssystem.com/manual_breyl_system.php -
We are looking to improve on our setups for mold base machining. Are there any good quick change systems that can be used with mold base plates? Right now we are using good ole rails and clamps. There has to be a better faster way. Thanks!

Johnny M - what do you cut on your Awea? Job shop parts? Molds?

The company I work for is debating between the above 2 manufacturers for a new CNC. Yama Seiki offers a large bridge mill (VP2012) with a Fanuc 32M control for less money than YCM is offering for a C-Style frame machine (NTV-158B) with a Fanuc 31i control. Thoughts? The company I work for specializes in plastic injection mold building. I have reservations about the 32M control being a standard cnc control (no look ahead). Both machines would have CAT50 - 10k spindles.
