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

- aircraft parts

- wind tunnel models


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.

Halloween pumpkin (free CAD download file)

Designed in Siemens NX 8.5

Halloween pumpkin model in 3D. Done after my colleague sent me his model that i found very inspirative.
3D printed version is done after I uploaded this model to www.myminifactory.com where it was 3D printed and painted. It can be produced as one part or with removable top, so it can be used as candleholder.

Pumpkin shape is done in Shape Studio module as X-Form, but eyes and mouth are done in modeling module.

How to put 3D measurements to drafting list

Designed in Siemens NX 7.5

One nice technique that can be used to put dimensions of parts of some assembly inside tables in drafting. In my case i had to make cut list of few thousands steel beams used in assembly. It would not be some huge problem if beams in assembly had 90° cut on both sides but... as you can see on picture below it have two surface cuts on both ends and these cuts are on some distance from actual extrude used to make base length of beam. So we can not use extrude parameters as length of beam.

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.
