Hi and thank You for visiting my blog.

This blog is about my professional work, projects I have been working on, and some funny and interesting things about mechanical engineers. On these pages You can find some of my projects, as I work for army and I am not able to enclose all projects I have been working on.

My most recent designs You can find in posts below.

For more interesting projects You can follow labels, such as:

- aircraft engine blades

You can download some of my models, posts with files for download are labeled free model download.

or You can go to INDEX page and search through list of all projects on this blog.

Info about me is on ABOUT ME page, where You can see my professional CV and some info about my skills and professional knowledge.

For all questions about my work, projects, blog or job offers contact me over e-mail or Skype. E-mail form and Skype Add Me link are on CONTACT ME page.

For those who are interested in learning new stuff about Siemens NX program I made NX TUTORIALS page, where I will post some tips and tricks about how to use NX more efficiently.

Blisk model for CAM (free CAD download file) (video)

Designed in Siemens NX8

A blisk (or bladed disk) is a single engine component consisting of a rotor disk and blades, which may be either integrally cast, machined from a solid piece of material, or made by welding individual blades to the rotor disk. The term is used mainly in aerospace engine design. The word is a portmanteau of blade and disk, the two components it replaces in turbomachinery. Blisks may also be known as integrally bladed rotors (IBR).

This model is made for my colleague who is working CAM and he needed blisk model for his CAM project (you can see movie of CAM processes in this post). This is not model of real blisk as it is designed by edit of real turbo engine blade and merging it with custom disk, it is designed to be machined from a solid peace of material. This blade is only for show of CAM processes needed for machining this kind of model.

My colleague give me permission to share his video on my blog.
"this is turbo-machining strategy of nx cam, this video show preparation for rough mill turbo-machining and blend semi finish" 


  1. This is a complex aerospace part, I have used NX turbomachining module. Hope you can enjoy.

  2. Hey there! I will be looking forward to visit your page again and for your other posts as well. Thank you for sharing your thoughts about cad design jobs. I'm glad to stop by your site and know more about cad design jobs. This is a good read. Keep it up!
    Beginning in the 1980s computer-aided design programs reduced the need of draftsmen significantly, especially in small to mid-sized companies. Their affordability and ability to run on personal computers also allowed engineers to do their own drafting work, eliminating the need for entire departments. In today's world, many students in universities do not learn manual drafting techniques because they are not required to do so. The days of hand drawing for final drawings are all but over. Universities no longer require the use of protractors and compasses to create drawings, instead there are several classes that focus on the use of CAD software.
    One of the principal duties and responsibilities of having cad design jobs is to perform job responsibilities with minimal supervision and with the utmost sense of urgency.

  3. Actually we are doing a project related to cycloid gear. for machining we require the CAD diagram . so please me help how to draw epicycloid and hypo cycloid using any of the CAD software like Autocad or PRO-E etc....

    Solid works

    1. I can tell you how to do it in NX... do you want me to do it?
