Had a bad thing happen back in the day. Used a water based coolant and it caused corrosion on the Mag. After plating we got orange peel. The shop lost big money. After that we stored in process parts submerged in Kerosene. Ya sounds crazy, the idea was storing parts in a oxygen free invironment. Probably a better way now, but it worked and we never had a fire.

Multi-angle workpiece holding
Cad-Camr replied to Marshal's topic in Machining, Tools, Cutting & Probing
In some cases we will increase the stock length on the end we hold on to. we have also machined a shape on the clamping end that aids in part orientation or the timing of particular features for future operations. -
I have that problem when i try to save a tool in any other catagory than undefined. If you have saved your insert Ball Mill in the Ball End Mill Catagory Try changing it to the undefined catagory.

Maintain your depth cuts. You dont have to ramp. takes too much time. Depth should be aroud 50% of tool Dia and I would use Multi-pass with a .002-.003 thou finish pass. That should reduce your 4 min cut time. Let us know what works best.
-
Forget the ramp. Rough drill 1 hole in the center of the slot a little bigger than your End Mill and drop in and 2d contour it. you will save time.

Better metric tool libraries
Cad-Camr replied to Reijo Heurlin from Zenex Finland's topic in Industrial Forum
Tool Libraries are designed to be modified for your specific needs. It would be impossible to design one for all applications. I have 5 different Tool Libraries that are set up for different material types. I also have machine specific Tool Libraries that are customized to take advantage of higher spindle speeds. -
Use a good rich mix on your coolant or use tapping fluid if possible and peck tap if you have that capability.
-
In the screen shot your showing I drag the tool I want up to the part tool list and it retains its library tool #. Then I change it to what I want. You might look in properties under tool setting and see if the box labeled assign tools sequentially is checked. I have had similar problems and just edited my tool numbers.
-
Be sure to include what level of mastercam you are using.
-
How old is old. We have rigid tapping on ours and they date back to '94. Ive never heard of using G95. On non-rigid machines we used spring heads.
-
Your geometry might consist of splines not arcs BTW Welcome to the Forum
-
I did that once

Geometry Groups do you use them?
Cad-Camr replied to Ron Branch @ Verisurf's topic in Industrial Forum
We also make a habit of keeping the groups manager cleared out so we dont experience the "ops manager shuffle" but we call it getting masterf*#$ed. -
I was getting the same thing last week and it would post everything but 90 degrees. So Iwent back into the WCS and created the views instead of copying Top, Front etc. and then It worked with no error message. Go figure!
-
Ive heard good revues about them. What would be the advantage of this machine over a Haas?
-
The ramping functions are nice to use here and there but I would drill a hole slightly larger than the End Mill at the start point, drop the tool in and 2d contour for rough and finish with another tool. Ramp tool paths arnt very efficient.My 2c

We also run a Net Hasp which is located on the server. Mcam and mcedit are on each work station. Mcam source and code files are on the server. so is mcedit on your machine or the server?

Geometry Groups do you use them?
Cad-Camr replied to Ron Branch @ Verisurf's topic in Industrial Forum
We are running version X MR2. If you have geometry groups it jacks-up the operations manager. It will take toolpath operations and combine them with operations that use another tool and that toolpath group will disappear. I cant be the only one this has happened to. -
Its funny how people in the "planning department" dont consider the manufacturing process when they define the required material size. The job takes longer with added operations. They look good for saving money on the stock and manufacturing looks bad for taking to long. I would rather do it all myself.
-
Gives you the data to keep your machines as accurate as they can be. A must for close tolerance work. We dont have one but we have it done by our service company.

Its been awhile but create the lettering toolpath above the part and project it onto the "Surface" of the part using surface project toolpath. I also created the surface at the radius where the tip of the tool will cut. Guhring High Helix drills work good on Delrin Feed and speed is a pretty broad window. Good Luck
-
Ideally your entry arc is at 180 deg from start point with a 1/2 pitch move in Z. If you check perp entry you should be able to use comp. I have used overcut in certain cases to adjust for any radius present on the insert.
-
Yes, Each operation can have its own feedrate. Look in the properties, Tool settings at the top of the Operation Manager and see what the setting is under feed calculation. Mine is set at from tool.
-
You can transform the Toolpath from the Toolpaths menu : Transform Toolpath. Then you can Xform Translate the Geo from the Xform Menu:Xform Translate.

It took me 5 years at 5 different companies to break thru the glass ceiling. It is difficult to get started. Keep knockin on doors. Let your skills do the talking. There's a reason your rollaway has wheels on it. Good Luck
