Create one or more isoparametric curves taking into account the tool of the screw milling operation. We can also take into account the center offset.

It's paticularly true for screw milling, having a constant or evolving step regardless of the screw body shape (cylindrical or conical,...) and the helix section.

 

 

This function can also be used to quickly create one or more tilting curves for five axes operations (this avoids to use the isoparametric function in Design and have to do some transformations to have it at the good place).

 

 

Operation

 

First, we have to define the reference surface, the tool (ball nose, radiused mill or side mill) as well as the isoparametric parameters.

 

Isoparametric

 

Face:

Shape 1 <2221>Face(29)

Tool parameter (Radiused mill)

Tool Corner Radius

2mm

 

Tool Diameter

10mm

Number of isoparametrics:

Basify
 
Define the face from which we will extract and create isoparametric curves.
   
Define the tool corner radius:
  • If the radius is null, the tool will be assimilated as a side mill.
  • If the corner radius is smaller than the tool radius the tool will be assimilated as a radiused mill.
  • If the corner radius is equal to the tool radius, the tool will be assimilated as a ball nose mill.
   
Define the tool diameter.
   
Adjust the isoparametric curve parameters (type, location, number). It works the same way as the isoparametric function in design.
   
Allow to basify the sketches if we want to modify them.By default the sketches are associatives.
 

 

 

1. First solution

Settings

 

Around axis

 

Revolution axis:

Shape 1 <2221>Face(29)

Offset center value:

2mm

 

Vertical direction:

Absolute Z Axis

 
 		 Once the face is selected and the isoparametric parameters settled it's required to:
 

1- Activate the option "Around axis"

2- Select the part revolution axis. This one is either X+ or Y+.

3- Enter the center offset value then select the reference surface.

In this case, the vertical is necessarily Z+ and we take into account the

fourth revolution axis.  

4- Validate the parameters by clicking on the green check mark.

 

 

 

2. Second solution

Settings

 

Around axis

 

Revolution axis:

Shape 1 <2221>Face(29)

Offset center value:

 

 

Vertical direction:

Absolute Z Axis

 
 		 Once the face is selected and the isoparametric parameters settled it's required to:

 

1- Select the vertical direction. Usually it's Z+.

2- Validate the parameters by clicking on the green check mark.

 

 

 

 

 

  • The curve created is associative meaning the curve will follow if the part positioning change.
