Holes and imports standard Thread in CATIA

One of the most commonly used tools in CATIA is Hole. With the help of this command, the possibility of creating a hole with the specifications and standards is provided on the surfaces. The drilling process is summarized as follows:

first, create a cylinder of 200 mm radius and 100 mm height then click the Hole command from the sketch – Based Features toolbar in Part design. Next, click the desired surface. The hole is placed in a position on the surface.

 

 

 

The following window is runs:

 

Click on the sketch icon. The center of the circle is displayed with a point where determine the exact coordinates. After moving the point click on Exit Workbench.

 

With the type tab change the type of hole for different screws and change the desired size. With Thread Definition tab thread the hole. Finally, the Hole is created on the surface by clicking on OK.

Standard sizes in Drilling

In design process Use standard sizes for holes in order to produce holes with standard drill. The use of unusual measurements is not recommended in the design of holes because they require special equipment purchase and therefore increases the cost of production.

 

Holes with flat end

It is recommended that in the design of blind holes, the bottom of the hole is not flat and it is considered a cone. machining operations of The holes with flat end is too difficult. Furthermore, since the construction of blind holes with the flat end requires special instruments, it increases the cost and time of the product production.

Hole interference with internal holes

In the design of the product, it is recommended to avoid holes that interfere with the internal holes in the piece. Otherwise, the drill bit is likely to be deflected from its original path or drill.

Imperfect holes

Avoid designing imperfect holes because in the event that a large part of the hole is out of the piece, it is likely that the drill deviates from its proper path. This problem will intensify if the hole axis is on the edge of the piece or very close to it. If after all the options have been checked, there's no other way than to use an imperfect hole, make sure at least 75% of the hole area is inside the piece.

Deep holes

Avoid deep and narrow holes in the design of the product, as they are difficult to machining operation. The drills with a narrow diameter are easily distracting from their paths, and their chances of breaking are high. it is recommended that the ratio of the depth to the hole diameter be less than 3.

 

Top and bottom surfaces

The design of the holes should be such that the hole's top and bottom surfaces are completely perpendicular to its axis. If drill tip enters a non-orthogonal plate on its axis during drilling, the drill will exit the specified path.

 

 

Add Hole Standards to CATIA

In order to add drill standards to CATIA and use them in the Hole instruction, we perform the following:

First, copy the attachment files to the CATIA installation path:

Download Drilling And Thread Standards

C:\Program Files \Dassault Systemes \B25 \intel_a \resources \standard \thread

Then, close the CATIA then open that again, other standards are created in the Thread Definition tab in the Type drop-down menu. To use these standards, enable Threaded option.

Command template for CATIA according AutoCAD commands

As you know the use the command box in CAD software helps to design more easily and quickly. For example in AutoCAD to drew "Line" if you just type "L" in command box the “Line” be called. There is this ability in CATIA too, but most of users don’t use it.

Spadantechnic group customized CATIA commands according to AutoCAD and release it.

note: you don't need type "c:"

CATIA App for gears and sprocket and Bearings

Perhaps you prefer insert gears from standard parts in internet or other CAD software due to its difficult to design them in CATIA. Aided this application you could parametric design some of common gears ,Sprockets,Bearings (Ball Bearing & Roller Bearing) and convert text to sketch.

This app has 4 tabs

First tab: you can create Spur, Helical, Bevel, Spiral Bevel, internal, rack and worm gear

Second tab: you can create Sprocket from table

Third Tab: you can convert text to Sketch (it support Arabic and Persian text by its converter)

Forth tab: you can create some of common Ball bearings and Roller Bearings from table.

Abaqus for CATIA AFC (DS SIMULIA V5 PLUGIN)

ABAQUS for CATIA (AFC), the software tool, uses the powerful pre- and post-processing capability of CATIA V5 to set up problems for solution using the versatile FEA solver, ABAQUS.  Currently, AFC is capable of solving problems involving linear and non-linear static as well as thermal analyses.[ABAQUS for CATIA V5  Tutorials AFC V2.5,Nader G. Zamani University of Windsor &  Shuvra Das University of Detroit Mercy]

Abaqus for CATIA takes the existing functionality of Abaqus Standard and integrates this within the CATIA environment. The result is advanced functionality that extends beyond the CATIA analysis tools, working on native CATIA data within the standard CATIA interface. Abaqus for CATIA offers thermal and basic non-linear structural analysis capabilities within the CATIA Environment.

Key Features:

  • Assembly of analysis documents
  • Sub-modelling available for static and dynamic analysis
  • Cyclic symmetry allows modelling of an entire 360⁰ structure
  • Define composite layup and import composite properties
  • Utilise CATIA Design Tables to define component tables
  • High-fidelity contact

Benefits:

  • Integrated into CATIA
  • Realistic and robust modelling
  • Easily compare design alternatives using parameters and design tables
  • Optimise structures to meet targets
  • Deploy proven workflows to designers
  • Have confidence in results

Bevel Gear Assembly

Step 1

.Create 90 deg angle constraint between gears

 

 

Step 2

select plane definition from reference element toolbox then create a plane on pinion's addendum's center. 

 

Step 3

select plane definition from reference element toolbox then create a plane on main gear's diddendum's center. 

Step 5

.The bevel's cones should be coincidence by coincidence constraint

Step 5

The planes that have created in steps 2 and 3 should should be coincidence by coincidence constraint
