Greetings from Jytra!

Despite of vast experience with NX software for almost 17 years, we suddenly landed into Siemens PLM License Server in a new computer. Below is the system configuration:

Operating System : Windows 7 Home Premium 64bit

Siemens PLM License Server Version: v8.2.1_win64_setup

When we are attempting to install the license server we were getting a series of error messages like below:

Java VM cannot be started

or

unable to start application - java virtual machine cannot be loaded

or

unable to start application - java virtual machine cannot be loaded
Class not registered.

Then we noticed that the system is missing with Java Run time Environment. Hence as a common best practice, landed on to Oracle website and downloaded the latest JRE for Windows 64bit and installed.

When we tried again, we are getting the same message again and again. Repeated uninstall and install of JRE latest version didn't help.

Finally, we really realized is Simens PLM server is looking for a path as below:

C:\Program Files\Java\jre7\bin

However, the latest JRE 8 has a different installed path, jre7 is replaced by some thing like jre 8.2.1. So this is the reason Siemens License Server is unable to find the execuatable for jre7. They are still stuck with jre7 for some internal reasons.

So, we followed the below final steps to get rid of these issues:

  1. Uninstall all Java Runtime versions from the computer.
  2. Restart the computer
  3. Search for java 7 for Windows 7 64bit operation system (or as per your Operating system). In our case, we found the latest JRE as "jre-7u80-windows-x64.exe".
  4. Set the environment variable as :  My computer-> right click -> properties -> Advanced System Settings -> Environment Variables -> Create/Edit the variable (_JAVA_OPTIONS = -Xmx512M)
  5. Please note "_JAVA_OPTIONS" has to be pasted in Variable Name field and "-Xmx512M" to be pasted in variable value field. Make sure there are no extra spaces in above strings.
  6. Try installing jre7 downloaded above in your pc. It should work fine.
  7. In case of any error, change the above Environment variable as "_JAVA_OPTIONS = Xmx512M"
  8. After this you install Siemens PLM License server, it should work fine.
  9. Still if you face any problem, add the path of your java.exe in "Path" Environment variable at the end after a ; (Example: Path = .......;C:\Program Files\Java\jre7\bin;C:\Program Files\Java\jre7\bin\java.exe. ). Do not delete any previous values in Path variable. Just add the new java paths at the end separated by '.

Now NX license server should work perfect.

Hope these steps will save your time and help you in flawless installations of Siemens PLM License Server.

Thanks & Best Regards,

Jytra Engineering Services is one of the best training institutes in Hyderabad, Andhra Pradesh. Jytra has been offering various training programs since 2006. Today Jytra is offering Unigraphics NX, Solid Edge trainings in association wit Siemens PLM Software. Also we offer AutoCAD 2D&3D training which is affiliated to SBTET, Government of Andhra Pradesh.

Unlike other training institutes in Hyderabad, Jytra focus mainly quality of the training. We simply don\'t deploy inexperienced faculty to conduct the training. we give more emphasis on application knowledge rather than teaching mere software commands. Many training institutes in Hyderabad use couterfeit software, offer programs for a cheaper price and terminate the course incompleted. Jytra Engineering Services uses genuine software tools and offers systematic training as per the predefined schedule.

In order to distinguish ourselves from other training institutes in Hyderabad, we associated with globally leading CAD, CAM and PLM Software developers to provide in depth training to our studetns. We use practical drawings for practcing the sofwate unlike other training institutes in Hyderabad who use basic exercises from engineering drawing books. These exercises doesn\'t help in applying the software in real time world.

Apart form own certification like other training institutes in Hyderabad, Jytra also offers certifications from SBTET, Siemens, ProgeSoft etc. which are recognized at a wider spectrum.

The whole world is under tremendous financial pressure these days. Everyone is fearing now to invest huge capital on new projects. The Automotive sector is undergoing recession now especially in North America. The financial trouble of Big 3 (General Motors, Ford Motors and Chrysler Motors) is very discouraging for the entire mechanical engineering community. Most Tier 1, Tier 2, Tier 3 suppliers, service providers and sub-contractors will be affected by this. The automotve sales are dropped by over 30% this year compared to same quarter last year.

Most companies are declaring holidays, forcing employees to apply leaves, cutting-down production etc. However, the new product development, Research & Development activities cannot be stopped completely. So is the case for engineering changes and revisions. Thus companies should identify alternate sources to perform their activities at lower prices. Outsourcing is the best solution to overcome this problem.

Outsourcing Engineering Services is little difficult compared to other services. Following are the critial aspects in finding a competent service provider:

  • Technical skills

  • Commitment

  • Regular Communication

  • Infrastructure and facilities to deliver the tasks on-time

  • Cost competitiveness

There are very few companies in the world to handle the projects with above qualifications. Before awarding projects, the client is advised to check the portfolio and testimonials of the service provider and visit the facility if possible.

Jytra Engineering Services has several years of practical application knowledge of AutoCAD software. We have applied AutoCAD software to various projects in different domains. Thus we have strong application knowledge about the software.

We have designed various AutoCAD training programs right from beginners level to advanced user level including software customization. Special focus will be given in applying the software in best ways to various projects. There are several custom designed exercises, course manuals and dummy projects to ensure effective training. Like other training centers, we don''t focus only software commands. We strongly believe that application knowledge is more important than merely learning the software tool. The structured training plan will ensure the trainees to learn the features, commands and tools available in software to a greater depth. The second part of the program involves the trainees to work projects and practical drawings to effectively apply various methods to the project.

The designers who work on regular projects only handles the training program, we use dedicated faculty members. This help both trainees and designers to explore the software in a right way.

If you notice the problem of Graphics Display, especially in sketch dimensions. It is a problem that sketch dimensions will appear as zig zag lines, dimensions will be clumsy and values cannot be read unless we try to edit them. The possible reasons are:

(i) One reason is if we install 32bit version of NX on a 64bit computer, it is more likely to cause the graphics problem and vice-versa.

(ii) If the Graphics capacity of the computer is not sufficient to run NX, we will notice this problem. But this will be more on 3D geometry like solids and surfaces. Even the wireframe geometry will not be proper. Sketch dimensions are expected to appear correctly in this case.

For further help you may contact Siemens Global Technical Access Center (GTAC).

Microsoft Office provides a nice option to send automatic and custom emails to a group of recipients with custom names, greetings etc. I have explained the step by step procedure to set up your first mail merge.

Following are the steps:

  • Start your “office outlook” connected and running in your computer.

  • Prepare a list of email addresses in excel sheet.

  • Open MS word.

  • Click on Mailings tab.

  • Click on “select recipients” and choose “use existing list”

  • Select the excel file you created for email ids.

  • Click on “Start mail merge” and select “letters” option.

  • Compose your message in MS Word itself.

  • You can use “Insert Merge Field” option to choose excel filelds like greeting, recipient name etc. Names will change for individual recipients to create an appearance like it is a custom mail rather than group mail.

  • Click on “Finish & Merge”.

  • Choose “Send email messages” option.

  • In the “to” field, select email format from the drop down list.

  • Enter the subject line.

  • Click OK, your emails will be sent one after the other from your outlook email account.

These steps are written for Microsoft Office 2007. More or less it will be similar for Office 2003 also, let me know if you need any more help.

There is a limitation in using Symbolic Thread in Wave Geometry Linking. You will be able to select only Body for linking, not thread curves. Even promotion of bodies doesn''t support this.

In my opinion, it is better to recreate thread on Linked Body and link the thread parameters through interpart expressions. So that separately they are associative to main part.

Share with us, if there is a better solution.

Selective Laser Sintering (SLS) is an additive Rapid Prototyping (RP) technique that uses a high power laser (like CO2 beam) to fuse small particles of plastic or metal powder into desired 3D shape. The laser selectively fuses powdered material by scanning cross-sections generated from a 3D digital description of the part (from CAD data) on the surface of a powder bed.

After the first cross-section is sintered, the powder bed is lowered by one layer thickness so that the laser beam will sinter the next layer of part. The process repeats until the complete geometry is sintered from powder.

SLS RP technique can be used for wide range of materials like polymers (nylon, glass filled or with other fillers, polystyrene), metals like steel, titanium, alloy mixtures and composites. Green sand also can be used in this process. However, these powders will be specially prepared by manufacturers to suit a particular SLS machine.

This is most powerful RP technique to form complex geometric shapes and even the assemblies. Almost any geometry which can be modeled in CAD can be produced physically.

SLS does not require support structures unlike other RP processes such as Stereolithography (SLA) and Fused Deposition Modeling (FDM) due to the fact that part being built is always surrounded by unsintered powder all the time. The part can be directly taken out from powder after the sintering process is completed. The remained powder can be reused in machine with appropriate combination with unused powder.

In Hyderabad, Andhra Pradesh, India, the Department of Mechanical Engineering of Osmania University has procured a SLS machine recently from EOS Gmbh.

Siemens UGS will be launching Unigraphics NX 7.0 Software Release with 3D HD feature to provide better visual analysis. This feature will include new visual environment into Unigraphics software including Teamcenter PLM Software. Application users can easily develop and interpret the visual product data to improve their design speed and decision making. They can evaluate the product design on key factors such as release status, weight thresholds, material type, delivery status, mock up etc.

Instead of the conventional static 2D graphical format, 3DHD  promotes a higher definition visual representation of 3D data. In addition, the software will display interactive tags on screen, which when selected, will deliver more detailed information about the product or sub assembly. Part numbers, Bill of Materials (BOM), material data etc. can be integrated to the part. This eliminates the need for engineers to manually surf through other design documents.

The HD3D analytics capabilities will also be implemented in Check-mate software.

Today we would like to share the boundary machining methodology I tried recently. In one of my recent project on Aluminum machining, I have nested four parts. My intention was to create four different parts from a single stock. It includes the rough cavity cut and finish fixed contour cut.

I have used #8 counter sunk screw to hold the part and used a 1/8″ dowel pin to avoid rotation of part. 1/8″ Ball nose cutter was used for entire machining.

I normally prefer to use a single cutter for complete machining which eliminates the need of “Z” point reset.

Instead of machining the unnecessary stock material, I have created a rough boundary against each part which is slightly greater than the tool diameter. I wanted to separate the remaining stock in block form itself instead of machining it into chips.

I have taken care to use the transfer plane as clearance plane instead of previous plane at each level of cut. Well, it all worked well except for one problem. There was a chunk of island remained after the boundary cut which was separated from parts. I have not cleared the bottom surface of material so that this island can fall down.

Hence, it remained inside the pocket hindering the tool movement in successive cuts. Luckily I was watching the machine that time, slowed down the cutting speed and carefully removed the island. It was almost breaking the cutter.

So, here is the lesson I learnt. It is a very good practice to do the boundary machining with clearance plane transfer (don’t forget this to avoid cutter fouling with in process work piece). You have to make sure the solid scrap material will fall down automatically after its separation from the blank stock.

This method can save up to 30 to 40% of overall machining time.

Hope you found this article useful.
