Thank you. 

In my scenario  I only need run treadmill  on other side.  All features Blind and through hole as well as pocket I can run from one side. Only thread  because of direction of taper I will  probably  have to run on oposite side.

Thank you for advice.  

Yes I have two vices. 

I will try to do this way.

  It still require to take out part from one vice and put it to second, but at least getting finished  part.

Ok. I will try do test. 

Taking out part from vice and flip them and put them in the fixture for taping  and remove them will take about 2 minutes !!!!!!!

I am trying to speed up process .

I have 200 parts and probably more in the future so making it in one OP would be more efficient . I think.

You will have to do this thread from the other side, unless you happen to have a reverse taper thread mill that is.

 

in mastercam you can add a taper to the operation.

 

Thank  you. I will ask ISCAR  about putting  insert in opposite direction.

Hi

I have to do NPT 3/4-14 internal thread in 4140  0.75 thick plate.

There some pockets on the top of plate and coupler will be screw on the other side of plate.  Can I do it in one operation ( the taper will be wider on the bottom then on the top) using  ISCAR indexable  threading endmill with NPT 14 insert (11 tooth) ?  Should I use  minus value for taper , going from top to bottom?

Any suggestion on feed and speed  how many passes?

Any help appreciate.

Thank you very much. That is what I am looking for. I find it yesterday on You Tube after learning that I need using angle head.

Thaks evrybody for direction.

You have to create and use an angle head. 

Can you show me how to do it please.

we have old CNC machine with with manually turning head and Funuc controller and processor for it.. I would like to be able to program it with Mastercam with head turned first 90 degree and later switch it to 60 degree. 

My question is how it can be done with Mastercam. Can you guys help me with example of couple holes and slot and face.

Got a 4th on your VMC?

No just 3 axis.

Do you have a manual lathe you can use? I am assuming you will round stock?

 

I am attaching Mastercam 2020 file with the part and machine I am going to use.

Yes. Stock will be turning on manual lathe.

Thank you guys.

But I have only in my disposal Haas VF 3 axis mill and will make 2 of those. We also have time to do it.

JP is correct. If you are trying to do this on a 3 Axis mill you will have to do multiple setups and it will take a long time.

You should set the part up in Mastercam and select the machine you are going to use so that everyone is not guessing on how you intend to do this. Then attach the Mastercam file.

Thank you i will set part in Mastercam tommorow and post again.

 

 

Hi

I would like to get some help with attach part.

I was thinking to start with operation one putting round stock into big chuck and making flats. Then flip it put those flats into wise and shape rest of it.  What toolpaths would be the best for roughing and then finishing. Any help appreciated.

What version of Mastercam?

2020

More then 100 viewers, and no words? Anybody please>

Try to use FBM drilling cycle to speed up programming process. But can't figured out couple of things.

1. Why I cant change diameter of the hole in Hole Dedection -Hole Mapping - all holes should be 0.8125 but they put different diameters on CAD model and Mastercam read those value.     I would like to change it. How it can be done? Its looks like diameter column is inactive.

2.Holes are countersign for M 20 bolts how can I make FBD makes those countersign holes automatically?

Any help appreciated.

No problem here you go. All I ask is you pass it on to others like i have done for many years on this forum.

Pass it on

Have a good night.

Thank you I got it.  Good night .Stay safe.

If this requires a sharp point that the bottom of the "V" a chamfer/spot/mill ain't gonna get it.  You could lay the part at a 45 deg angle and use a regular endmill.

 

I' done this before by using my machining center as a Shaper, that is as long as you have spindle orientation.  I ground a piece of HSS to a sharp point and it worked great in Aluminum (using AL tap magic).

 0.03 radius on the tip of the tool is OK. Thank you for suggestion.

All good John just being the crazy person in the room is all.

You guys are amazing. Thank you.

It would be to much if I will ask for Mastercam file with all what you showing.

Create the center lines for the knurl above the part in 2D mode in the pattern that is required. Then project them to the surface. Then use a contour toolpath with the Compensation type set to "Off" to follow the lines. Set you depth as required.

 

Thank you for quick responce.

I like the idea but is depth will be constant on the curved surface even with 2D contour path?

hi 

I have a part which need to have knurl on top curves surface.

  90 degree groove  0.03 deep 0.125"  apart. See part and picture of groove.

How it should be programmed in Mastercam  what toolpath would be the best for it ? I have 90 degree Spot #9 chamfer cutter.

3-480-092-016.x_t

Make it in one shot or with couple approaching distance "multipasses" .

+1000 as it will want to pull down with that dovetail shape!

What you mean +1000 ? How about toolpath?

Hi

I have to make 60 degree dovetail in 4140 steel. I have 60 degree HSS dovetail cutter. What toolpath should I use ? depth of cut or approach distant. Should I rough dovetali with another cutter using flowlaine toolpath? I already mill slot.

Any help appreciated.
