hole axis

Helo Foks

Just wondering what is the best method to select hole axis to make our view aligned with the hole for a 5 axis part.

 

We want to do 3+2 way, so manual creation of view is important.

 

It is easy if hole openings form a true circle, How about if hole openings fall on a 3D surf.?

 

I can prepare it from Solidworks but how 2 accomplish in MC.

Follow the links,

Best of all it is free and works really well.

There is an easy way if you don't have

the hole axis chook too.

Create a surface from the hole

Untrim the surface

Now you have a cylinder

Draw an edge curve on each end of the cylinder

Now you have 2 circles in space.

Draw a 3D line between the centers of the 2 circles

That is the C/L of the hole

[Ron Branch @ 5th Axis]

Yes Hole axis. What we do is give the user the ability to create a circle. You can then create a center point for that circle as well as a vector line above and below the hole in question. Also the hole axis add-on is free and does all of what I just described with one mouse click. This add-on also has Notepad which allows you to save notes with the Mastercam file itself. In older versions you have to create notes for the files as drafting and save on a level. with notepad you can create all the note you want and it is saved without having to save that information as drafting on a level and is accessible at anytime.

 

Verisurf X3 Downloads.

 

Verisurf X2MR2 Downloads.

 

You did not say what version so here are links to 2 downloads versions we have. Go to the bottom of the page and you will see the add-on. Also you have 30 days of access to other tools we have like Reverse, MBD, and others things. If I can be of any assistance just email me.

 

Have a good day.

This is a great c-hook, i use it frequently. Thanks to Ernie for providing it free of charge, another function that i wish he would provide is the capability to create the pierce point when hole does exit on a 3-d surface.

In Mastercam you can project that point to the surface using the project and the Normal. On the Xform/project pick surfaces as shown in this picture:

 

 

Now the point you created with hole axis can be projected to the 3d surface that it intersects normal to that surface.

 

Now if you want it to be projected along the vector of the hole that is a different approach. The above is using the surface normal as the projecting method. This way uses the Normal of the Vector created by the Hole Axis Chook. You would need to create a C-plane using the vector created by the Hole Axis Chook. You then would go into your C-plane menu and pick Planes by Normal. Now you have created a C-Plane normal to that Vector. In the Xform project you would pick by View this time.(Note: Need to make sure your Gview is the same as your C-plane) Use the surface Method for the selection as shown in the picture. Now you have created a pierce point through the hole axis vector to the 3d surface.

 

We do have a free Chook that will do this just not updated for X yet. We hope to have it out in the next update. I will keep you updated.

Thanks Ron,

But as your explanation shows, there is quite a bit of work in creating this point along hole normal. I just completed a program where that pierce point feature would have helped out a bunch. Perhaps the older version is available?

[Ron Branch @ 5th Axis]

We have the pierce chook with our V9 Verisurf install. I do not know if it will work with just V9 or not.

I was good to learn all that, I'll do research on the verisurf and the chook thingy,

 

For now I'll try follow gcodes geometrical method.

 

Thank you everybody.

This is the 8 steps and 30 clicks that Hole Axis does in 1 step.

 

How to create C/L from trimmed hole surface. gcode provided these 3 steps.

 

1. Create a surface from the hole, Untrim the surface, now you have a cylinder. 3 clicks
   
2. Draw an edge curve on each end of the cylinder, now you have 2 circles in space. 5 clicks
   
3. Draw a 3D line between the centers of the 2 circles, which is the C/L of the hole. 3 clicks
    
   How to create the pierce point.
   
4. Set C-Plane or WCS using set Normal, select the created C/L and make sure its pointing in the correct direction. 4 clicks
   
5. Create center point on line for drilling. 2 clicks
   
6. Un-blank upper surface needed to get pierce point, intersection of line and surface. 3 clicks
   
7. Project center point onto upper surface to get the top Z position for the drilling start depth. 7 clicks
   
8. Clean up, re-trim or blank the upper surface back to its original state. 3 clicks

Good idea

 

I will have to add that option.

 

It will take the hole circle and project it up the C/L onto the face surface and use the highest point on the projected spline as the pierce point.

More about Hole axis.

 

Hole axis creates the point and vector needed for 5-axis drilling of holes. it also has the option to save its circle at the pierce point.

 

In order for pierce to work, don’t use the multi select button. Just run Hole Axis and start picking cylinder shaped surfaces (Holes), you will see that the created point is the upper pierce point. It will pierce the top most surface as you pick each hole, it uses the mouse selected surface point and projects it to the C/L then up the C/L vector using the screen view to decide what’s up, it will pierce the closest surface it encounters in that direction, it even looks at blanked surfaces because the top surface is usually trimmed out for the hole. The piercing works automatically for surface models but for solids you will need to select the top piercing face before selection the holes, so for solids it only pierces selected faces.
