Week 4 Challenge

AIM:

    Create Tooling axis and class B surface and create a solid from the provided class A surface. Then do drafting analysis and create the parting line.

INTRODUCTION:

CATIA:

         It means Computer-Aided Three-Dimensional Interactive Application.  It is computer aided designing software. This is software which is used to design 3D models with different workbenches.

   CLASS A SURFACE:

                 It is surface which is made by the designer. It is aesthetic surface and usable outside futures are on this surface.

  CLASS B SURFACE:

              It is bottom side surface of class A surface. It is made by class A surface. It is formed with thickness distance from class A surface.

  CLASS C SURFACE:

           It joins the both class A and class B surfaces. This surface is equal to the thickness of the component.

TOOLING AXIS:

• Class A surface or part is used to manually analysis which is best for tooling and create the axis perpendicular to the product. It is called tooling axis. Mould is open and closed by this axis.

PARTING LINE:

• Core and cavity meeting line is called parting line.

METHODOLOGY:

            

 

 

TOOLS:

1. Extract:

       This comment is used to create the required surface again. Which means copy the surface again for next operations.

2. Un trim:

      This tool is used to un trim the surface which means create the full surface of previous surface from current surface.

3. Trim:

      This tool is used to cut and eliminate the unwanted surface.

4. Extrapolated:

       This tool is used to increase the length of surface or area with the help of different option.

5. Offset:

    It is used to create the same surface again in required distance.

6. Edge Fillet:

    It is used to create sharp edges to round edges.

7. Boundary:

    It is used to form the boundary lines on opened surface.

8. Sweep:

    It is used to create the surface in required length from the profile.

9. Join:

 It is used to join the separate surfaces and create the single surface.

10. Close (Part command)

It is used to create the solid part from closed hollow part.

SURFACE A CLASS:

TOOLING AXIS OR TOOLING DIRECTION CREATION:

•   Tool moving direction is called tooling direction which means core and cavity are moving in one direction which is called tooling dircection.
•   Class A surface or part is used to manually create a axis and analysis by drafting analysis and chane the angle and fix the correct tooling axis. It is best for tooling and create the axis perpendicular to the product. It is called tooling axis. Mould is open and closed by this axis.

• First take the class A surface and manually analysis and fix the direction of tooling.
• Carefully watch and take this axis with the help of all types of views.
• First create the point on the base surface. Then create a line and create another line and change the angle which is clear the drafting angle that line fixed as tooling direction with the help of drafting analysis.
• Change some appearance to this line like thickness, colour, dot lines. Finally, it is called tooling axis. It is published for frequent uses.

             

DRAFTING ANALYSIS:

• Go to insert < analysis< feature draft analysis.
• Compass is fixed on the tooling axis.
• Then we click on the surface it showing different colour. This colour is used to analysis the drafting value of surface with the help of analysis table.
• In this surface fully green colour by means which drafting value is grater then 10 deg. We also edit the table and colour to analysis the different drafting value.

             

SURFACE B CLASS CREATION:

               Following procedures are used to create surface B class.

                   

1. Extract the input class A surface.
2. Offset the surface 2.5 mm
3. We got class B surface.

SURFACE C CLASS CREATION:

1. It is created by boundary lines or extract edges to create surface. In this part extract file method was used.
2. Extract the Class A edges. Smooth curve tool is used to change the smooth curves
3. This curve is extracted by sweep command’s draft option.

               

FINAL BASE PART:

1. Join command is used to join the surface A class and the surface B and C class. If the gaps are between two surfaces extrapolated commend is used extract and trim it. In this part it was followed. They Join themselves.
2. Finally, we got hollow product. In part bench close commend is used to get the solid model
3. It is again above drafting analysis process is used to analysis the drafting angle.

             

DRAFTING ANYLYSIS:

  Again, Same drafting analysis procedure is used to analysis the drafting angle of final part.

             

            

 PARTING LINE CREATION:

            Where the core and cavity is meating which line is called parting line. In this class A surface edge is parting line. So, extract the edge of the parting class A surface edge and created parting line.

                 

CONCLUSION:

               Different commends are used to create the surface A class, B class, C class. Then join and convert the solid. Finally solid product is created by CATIA software and drafting is analysed. Parting line of the part is crearted.
