S355 is a non-alloy European standard (EN 10025-2) structural steel, most commonly used after S235 where more strength is needed. It got great weldability and machinability, let us see more mechanical details of this steel.<br />
<h2>
Identification of Different S355</h2>
<div>
S - stands for structural steel</div>
<div>
355 - stands for minimum yield strength (though it will vary based on thickness, refer below section for more details)</div>
<div>
<br /></div>
<div>
Normally S355 will have following variation based on impact strength at different temperatures, as steel become more brittle when temperature drops. If your structure need to withstand -20°C, it's better and safer to choose S355J2. </div>
<div>
<div>
<br /></div>
<div>
S355JR - Can withstand an impact energy of 27J at +20°C</div>
<div>
S355J0 - Can withstand an impact energy of 27J at 0°C</div>
<div>
S355J2 - Can withstand an impact energy of 27J at -20°C</div>
<div>
S355K2 - Can withstand an impact energy of 27J at -30°C (40J at -20°C)</div>
</div>
<div>
<br /></div>
<div>
And sometime followed by a letter H, like S355J2H, here H stands for hollow section.</div>
<h2>
S355 Yield Strength</h2>
S355 is named based on it's minimum yield strength of 355 Mpa (N/mm2), However the yield strength reduces when you go up in thickness above 16 mm for flat products & hollow sections<br />
<br />
Here is the table showing reduction in yield strength based on thickness<br />
Up to 16 mm - 355 Mpa<br />
16 mm < t ≤ 40 mm - 345 Mpa<br />
40 mm < t ≤ 63 mm - 335 Mpa<br />
63 mm < t ≤ 80 mm - 325 Mpa<br />
80 mm < t ≤ 100 mm - 315 Mpa<br />
100 mm < t ≤ 150 mm - 295 Mpa<br />
<br />
<h2>
S355 Tensile Strength</h2>
S355 ultimate tensile strength ranges also varies based on thickness.<br />
Up to 3 mm - 510 Mpa to 680 Mpa<br />
3 mm < t ≤ 100 mm - 470 Mpa to 630 Mpa<br />
100 mm < t ≤ 150 mm - 450 Mpa to 600 Mpa<br />
<br />
<h2>
S355 Density</h2>
<div>
Density of S355 is 7850 kg/m3 like all other mild steel</div>
<h2>
S355 Hardness (Brinell Hardness - HB)</h2>
<div>
Hardness for S355 J2 ranges from 146 HB to 187 HB</div>
<h2>
S355 Young's Modulus</h2>
<div>
S355 Youngs's Modulus is 190 to 210 Gpa, in a conservative design go for 190 Gpa</div>
<h2>
S355 Equivalents</h2>
<h3>
S355 EN 10025:1990 Equivalent </h3>
<div>
S355J2 → S355J2G4 (1.0577)</div>

It’s annoying sometimes, when edges of circular parts like flanges not displayed properly, and mostly look like polygon instead of circular. Here is what you can try to improve the edge display quality on Pro Engineer Wildfire (Creo Elements Pro). Go to ‘View’ –> ‘Display Settings’ –> ‘Model Display…’. In the model display dialog box select the second tab Edge/Line. Here you can find a drop down menu under ‘Edge Quality’. Change the default value ‘Medium’ to ‘High’ or ‘Very High’ depending upon your need. Then press apply, you are done.<br />
If you want to keep this settings every time ProE (Creo) opens then you have to save it in Config file. Here is what you have to do, go to ‘Tools’ –> ‘Options’ . Type ‘edge_display_quality’ in the ‘Option’ field and select ‘Very_High’ from the drop down and click ‘Add / Change’ button. <br />

<p>
Duplex bearings are a set of two bearings  on a shaft with the inner and outer rings clamped together with preload to attain greater axial and radial rigidity. Duplex bearings also used to achieve additional capacity when insufficient space radially for larger bearings.</p>
<p>
Duplex bearings are machined as matched sets.  The pairs are furnished with the race faces ground to provide preload when installed. To accomplish this, a gap is provided between the inner races or outer race of the pair. When the bearings are installed and clamped axially, the gap is closed producing a preload on the bearings. There are three types duplex bearing arrangements commonly used and they are Back to Back, Face to Face and Tandem bearing arrangement. Bearings that are normally duplexed are angular contact ball bearings and tapered roller bearings.</p>
<h2>
Back to Back Bearing Arrangement (DB, O)</h2>
<p>

<div id="caption">
Back to back bearing arrangement,  gap is provided between inner races</div>
<p>
Back to Back bearing arrangement (also known as “DB arrangement”,  “O arrangement”) is a type of duplex bearing arrangement where the two half are placed so that contact angle lines of the bearing diverge inwardly. And these contact angle lines form ‘O’ shape, hence called as “O arrangement”. </p>
<p>

<div id="caption">
Back to back bearing - preload animation</div>
<p>
In back to back arrangement a gap is provided between inner races and when installed, this gap is closed and producing a preload on the bearings. DB arrangement has higher moment stiffness than the DF arrangement. Under the same preload, DB and DF have identical radial and axial stiffness.</p>
<h3>

<p>
Heavy radial loads, combined radial and thrust loads, reversing thrust load, moment loads</p>
<h2>
Face to Face Bearing Arrangement (DF, X)</h2>
<p>

<div id="caption">
Face to face bearing arrangement,  gap is provided between outer races</div>
<p>
Face to face bearing arrangement (also known as “DF arrangement”, “X arrangement”) is a type of duplex bearing arrangement where the two half are placed so that contact angle lines of the bearing converge inwardly. And these contact angle lines form ‘X’ shape, hence called as “X arrangement”. </p>
<p>
In face to face arrangement a gap is provided between outer races and when installed, this gap is closed and producing a preload on the bearings. DF arrangement has lower moment stiffness, so they must be spaced sufficiently to provide resistance to moment load.</p>
<h3>
Face to face bearing arrangement may used to carry</h3>
<p>
Heavy radial loads, combined radial and thrust loads, reversing thrust load</p>
<h2>
Tandem Bearing Arrangement (DT)</h2>
<img title="Tandem (DT) Bearing Arrangement" border="0" alt="Tandem-DT-Bearing-Arrangement" alt="Duplex-Bearing-Angular-Contact-Ball-Bearing" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhl6hxHQo8wf6knzBLF0PAAE5cK_tkG8rKLfy1_ctO0uDLtfV2Rd95hbTU2Jg8UXe1bYUNaaIBszYKjGtI4DmLuIhl7rzVsq2-qTo4v1qc09W7u49H3U6BCTqhE2hapqLT3kScziteFj8s/s320/tandem-dt-bearing-arrangement.jpg" />
<div id="caption">
Tandem bearing arrangement - Only accepts one directional thrust load</div>
<p>
Tandem bearing arrangement (also known as “DT arrangement”) is a type of duplex bearing arrangement where the two half are placed so that contact angle lines are parallel. This arrangement makes a very heavy duty thrust bearing arrangement, but it will not carry any radial load and accepts thrust loading in only one direction. DT has the same radial stiffness with equal preload as the DB/DF arrangement, but its axial stiffness is twice that of DB/DF arrangement with the same preload. </p>

</tbody></table></div><h2>1. Spur Gear Efficiency</h2><p>Spur gearing is a parallel shaft arrangement, and these gears can achieve much higher efficiencies compared to other gear types. Its efficiency varies from 94% to 98% with lower gear ratios.  </p><h2>2. Straight Bevel Gear Efficiency</h2><p>Straight bevel gearing is similar to spur gearing with perpendicular shaft arrangement. Like spur gearing these gears also only can handle lower gear ratios with higher efficiencies (93% to 97%).   </p><h2>3. Spiral Bevel Gear Efficiency</h2><p>Because of tooth shape and contact spiral bevel having less noise and vibrations compared to straight bevel gears, and thus having better efficiency (95% to 99%).   </p><h2>4. Worm Gear Efficiency</h2><p>Worm gear efficiency varies significantly when lead angle, friction factor and gear ratio changes.  </p><h3></h3><h3><font style="font-weight: bold"><u>Worm Gear Efficiency Calculation</u></font></h3><p>Use the  following <strong><em>gear efficiency equation</em></strong> to calculate efficiency of worm gears. </p><p><img style="border-right-width: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; margin-left: auto; border-left-width: 0px; margin-right: auto" title="Worm-Gear-Efficiency-Calculation-Equation" border="0" alt="Worm-Gear-Efficiency-Calculation-Equation" src="http://lh3.ggpht.com/_EhOQGW2GHBg/TMMdudDeqJI/AAAAAAAAIFk/w8_7_K67kyY/WormGearEfficiencyCalculationEquatio%5B1%5D.jpg?imgmax=800" width="198" height="114" /> Where f is the coefficient of friction for worm gears normally ranges from 0.06 to 0.02, p the pitch of the worm thread and r the mean radius of the worm. </p><h2>5.Hypoid Gear Efficiency </h2><p><img style="border-right-width: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; margin-left: auto; border-left-width: 0px; margin-right: auto" title="Hypoid-Gear" border="0" alt="Hypoid-Gear" src="http://lh3.ggpht.com/_EhOQGW2GHBg/TMMdu5LkD6I/AAAAAAAAIFo/hNg7QgpaC40/HypoidGear3.jpg?imgmax=800" width="368" height="201" /> </p><p>The efficiency of a hypoid gear is around 80-95% and can achieve very high gear ratios up to 200:1.</p><p> </p><h2>6.

Calculate pressure generated and force to engage/disengage - H6m6 fit example - Click on the image to download the calculator</div>
Interference and Transition fits can be used effectively connect machine elements. This calculator uses following formula to find the pressure generated with the designed connection.<br />
<img alt="Pressure interference fit formula" border="0" height="88px;/" src="https://lh5.ggpht.com/_EhOQGW2GHBg/SlXSIWu6t4I/AAAAAAAAHnA/Hk1UePzrw9M/s800/pressure-interference-fit-formula%5B5%5D.jpg" style="border-bottom: 0px; border-left: 0px; border-right: 0px; border-top: 0px; display: block; float: none; margin-left: auto; margin-right: auto;" title="Pressure interference fit formula" /> <br />
This data then can be used to optimize the design of the hub/shaft, or can be used to find the force to engage and disengage these parts, or can be used to find the maximum torque this connection can transmit without slippage.<br />
Above example shows a transition fit of H6/m6 between shaft and hub.<br />
To find tolerances for different fits refer<b> <a href="http://www.misumiusa.com/CategoryImages/Metric_2006_pdf/METRIC1835-1836.pdf" target="_blank">Tolerance Table for Regularly Used Fits</a></b><br />
For calculating minimum force to engage or disengage these parts we can use the following formula<br />
<pre>F = μ . pmax . A</pre>
Where μ is the friction between hub and shaft, A is the area of contact between shaft and hub.<br />
To calculate maximum torque which can be transmitted without slip can be found using following formula<br />
<pre>T = F . d/2</pre>

<i>Kris Berthold</i> added some additional calculations as well<br />
<br />
1. Minimum force required to engage/disengage as well as maximum (based on the minimum pressure generated)<br />
<br />
2. Added some conditional checks to tell you if a fit is metal-to-metal or a clearance fit, instead of just giving the #VALUE! error.<br />
<br />
3. Added some extra lines to calculate the min/max torque that can be transmitted based on the formula shown on the website<br />

<br />
Here are the steps to create an Involute Curve using the above equations in Pro/Engineer<br />
<br />
1. Create a datum curve using the option ‘From Equation’ <br />
<pre>Insert -> Model Datum -> Curve -> From Equation </pre><div align="center"><a href="http://lh6.ggpht.com/Shinto.Mathew/SLZH4Iv_uXI/AAAAAAAAFc0/IOy8dWYGevI/s1600-h/clip_image001%5B5%5D.jpg"><img alt="clip_image001" border="0" height="261" src="http://lh6.ggpht.com/Shinto.Mathew/SLZH58V0zSI/AAAAAAAAFc4/olDb89OSx_o/clip_image001_thumb%5B2%5D.jpg?imgmax=800" style="border-bottom-width: 0px; border-left-width: 0px; border-right-width: 0px; border-top-width: 0px;" width="258" /></a></div>2. Select a Coordinate System<br />
3. Select Cartesian as Coordinate System Type <br />
4. Input the following equations in the popup textpad <br />
<pre>a = 100
Theta = T * 360 * 2 /* for 720 degree involute
x = a * (cos (Theta) + (PI * Theta / 180) * sin (Theta))
y = a * (sin (Theta) - (PI * Theta / 180) * cos (Theta))
z = 0
</pre><p>Where 'T' is a Pro/Engineer system variable, and its value will vary from 0 to 1 during the execution of the program. You can control the angle of involute by changing value multiplication value after 'T'.</p><p>For example if you want to create an involute curve from 30° to 70°, just modify the equation of Theta to<br />
</p><pre>Theta = (T*(70-30))+30</pre><p>Also note that in Pro/Engineer you need to enter angle in degrees instead of radian to compute cos & sin.</p><br />
5. Save the File and close it. And Give Ok.<br />
Check your curve with the figure below.(Blue colour circle is the base circle)<br />

Here the sensing distance of inductive proximity sensors was almost reduced to 60%.</p><p>To determine the sensing distance for materials other than mild steel, a correction factor needs to be applied. Target material has a big effect on sensing distance of inductive proximity sensors. In order to determine the actual sensing distance for the target material, Multiply the nominal sensing distance by the correction factor.</p> <p>The correction factors listed below can be used as a general guideline.</p> <p><strong>Nominal Sensing Range x Correction Factor = Actual Sensing Range.</strong></p> <h2>Correction Factors (Allen-Bradley) </h2> <br /> <div align="center"> <table border="1" cellspacing="0" cellpadding="0" width="540" align="center"><tbody> <tr> <td valign="top" width="274"><strong>Target Material</strong> </td> <td valign="top" width="266"><strong>Approximate Correction Factor</strong> </td> </tr> <tr> <td valign="top" width="274">Mild Steel </td> <td valign="top" width="266">1.0 </td> </tr> <tr> <td valign="top" width="274">Stainless Steel </td> <td valign="top" width="266">0.85 </td> </tr> <tr> <td valign="top" width="274">Brass </td> <td valign="top" width="266">0.50 </td> </tr> <tr> <td valign="top" width="274">Aluminum </td> <td valign="top" width="266">0.45 </td> </tr> <tr> <td valign="top" width="274">Copper </td> <td valign="top" width="266">0.40 </td> </tr> </tbody></table> </div> <h2 align="left">Correction Factors (Keyence, Balluff, Omron)</h2> <p align="left"><img style="background-image: none; border-bottom: 0px; border-left: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top: 0px; border-right: 0px; padding-top: 0px" title="Proximity-Sensor-Sensing-Distance-And-Type-of-Metal" border="0" alt="Proximity-Sensor-Sensing-Distance-And-Type-of-Metal" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgxhbYmmne0yetRgGgbfBiVzTBcUK4kbZ0EbZ9IvaokwXFCNnPIQTpg8YH95YPAJYD_YkVBU_6Qg5NvDX1eZx43VTx8oLHWGJ2s34HAsP81RrV85rM0l12Fu317-Fz7qarRUN8aPVPmVL8/?imgmax=800" width="351" height="345" /></p> <p><img style="background-image: none; border-right-width: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px" title="Proximity-Sensor-Sensing-Distance-And-Type-of-Metal-Balluff" border="0" alt="Proximity-Sensor-Sensing-Distance-And-Type-of-Metal-Balluff" src="http://lh4.ggpht.com/_5qXARXRyYQQ/Tbmipc7N5YI/AAAAAAAAADY/MRY1vA2mC3w/Proximity-Sensor-Sensing-Distance-An%5B3%5D.jpg?imgmax=800" width="540" height="460" /><img style="background-image: none; border-right-width: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px" title="Proximity-Sensor-Sensing-Distance-And-Type-of-Metal-Omron" border="0" alt="Proximity-Sensor-Sensing-Distance-And-Type-of-Metal-Omron" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgEtOikqlAHJsgheFIuvbpqMmi7cAs5LXJvyxU3wGSCA7rej8jjNV57NDnJTxgbOo80Rw7l8l1v1KI5FLE4ZrroxiKBhTrLH-sTqIPnW_9PEstEcanbznBB9ICQFQfRPd5Be9rDklvDMhU/?imgmax=800" width="340" height="384" /></p><div class="blogger-post-footer"><p style="background:#FFFFE0 none repeat scroll 0 0; border:1px solid #E6DB55; margin:5px 2px; padding:3px; width:600px; height: auto;">

Flying like birds is one of the oldest dreams of man kind. And back in 1490 Leonardo Da Vinci’s flying machine concept brought us closer to achieving bird flight. Now engineers of Festo’s Bionic Learning Network achieved this amazing feat. Check out this concept animation.<br />

Festo’s flying bird (SmartBird), and its design inspired by herring gull. SmartBird weights only 0.45kg and can start, fly and land autonomously. The bird is powered with with a two stage helical gear motor with reduction ratio of 1:45.<br />

But while exporting it produced 'eWasOpenForWrite' error and unable to complete the export. The error read </p><blockquote>Un-handled exception has occurred in a component in your application. If you click Continue, the application will ignore this error and attempt to continue.</blockquote> <p>I immediately searched Autodesk discussion groups for ‘eWasOpenForWrite’ and found <a href="http://usa.autodesk.com/adsk/servlet/u/gsearch/results?siteID=123112&catID=123155&id=2088334&qt=eWasOpenForWrite&x=0&y=0" target="_blank">some suggestions</a>.  But to my dismay those suggestions didn't solve the problem. The unsuccessful suggestions I found in  Autodesk discussion groups  are </p> <p>1. Use ‘recoverall’ command to repair the drawing</p> <p>2. Unbind all ‘Xref’ blocks and purge the drawings</p> <p>3. Use ‘audit’ command with auto repair option set to ‘No’</p> <p>Then decided to do my own experiment, and found the following three solutions. </p> <h2>1. AutoCAD Mechanical 2004 Save As</h2> <p>In this method ‘save as’ the drawing in AutoCAD Mechanical 2004 format. Then close AutoCAD (note that you have to close AutoCAD entirely not just the drawing). And open the AutoCAD and open the saved drawing. </p> <h2>2. AutoCAD 2010 Save As</h2> <p>In this method save the drawing in plain AutoCAD (not as AutoCAD Mechanical) and close AutoCAD and reopen the file and try exporting layout to model.</p> <h2>3. Open with AutoCAD</h2> <p>Just close AutoCAD Mechanical and open plain AutoCAD and open the drawing in it and try export layout to model.</p><div class="blogger-post-footer"><p style="background:#FFFFE0 none repeat scroll 0 0; border:1px solid #E6DB55; margin:5px 2px; padding:3px; width:600px; height: auto;">
