NX improvements shown on PLM Europe 2015

PLM Europe is an annual conference, centered around Siemens PLM product line. Most of presenters are from Siemens PLM, showing the new features of the software and further development areas. There are also software partners and customers, showcasing the add-ons and examples of software use. Here I would share the things I found interesting and will give some comments regarding presented features. My overview covers mostly NX CAD. Smart innovation At the beginning, the tendencies in innovative technologies were presented, and Siemens PLM portfolio was shown to support the needs of these technologies and of today’s devices. This was mainly related to three topics: Digitization of early stages of product development System-driven product development So-called “Digital twin”, which is mainly about production simulation in Technomatix One more …

Replace components in a machined assembly

Overview Some time before, I promised to look at the special techniques which help to replace components in assemblies with machining features applied to them. In this article I’ll describe them in detail. In complex products, machining after assembly is a typical scenario. On the other hand, it is often required to replace components in a CAD assembly. It is done in at least two major cases: A design change is required, which involves replacing components with their updated versions A new design is being created based on the old one, which requires replacing a number of components with different ones. Therefore, it is often needed to replace components which have modeling features applied to them at the assembly level. In NX it is not very …

Free NX tutorials, part 1: The place of free tutorials in the learning process

I am often asked, especially after starting CADroad, if there are any free tutorials for NX. My answer is: “Yes there are, but if you are a new user, I believe they should be used with care”. I have taught NX for several years and sometimes I give links to these materials to my trainees to follow up the training. But I tell that they should understand their limitations before starting to using them. Here I explain what kind of tutorials are available for NX and what is the place of free tutorials in the learning process. In the next parts, the lists tutorials would be provided. Official training centers When someone ask me: “How do I study NX?”, my usual answer is to order …

Ideal PLM Technology Day Russia 2015, conference notes

Technology Day is an annual conference organized by the Siemens PLM partner ‘IDEAL PLM CIS’. Each year it gathers CAx and PLM experts from Russia and CIS. The conference had two main sections, one dedicated to NX and one to Teamcenter. Here I show what I have found interesting. Metrovagonmash The presentations were started with “Metrovagonmash”, a Russian designer and manufacturer of underground railway trains. First, the history of NX use was shown. The first models were developed in early nineties. At that time the 3D geometries were done in relatively low detail. Gradually, the level of detail was increasing, and project was run for transferring 2D drawings into 3D. Over 10k documents were processed resulting in around 11k unique 3D models of components. Currently, NX assemblies form …

Reduce time to CNC with NX CAM automation, part 2: CAM dialogs

This entry is part 2 of 2 in the series NX CAM automation

This entry is part 2 of 2 in the series NX CAM automationThis instruction shows how to redefine the NX CAM dialog boxes and save them as templates in order to record best manufacturing practices. The advantage of the method is simplicity, all customization work is done inside NX. Step-by-step instruction is given. 90% of automation in this video is done with this method: Why building NX CAM templates via dialogs? When creating a template, you reuse a set operations, each with its own individual parameters — tools, feeds and speeds, cutting parameters, etc. You make simplified selection for the actions that are unique for the new parts you manufacture with the template, this means that best practices can be reused and revised If best practices are recorded, less experienced users can be appointed to more complex tasks Area of use Detailed templates can be …

Reduce time to CNC with NX CAM automation, part 1: introduction

This entry is part 1 of 2 in the series NX CAM automation

This entry is part 1 of 2 in the series NX CAM automationIn NX, almost every aspect of CAM application can be customized. Customization can strongly improve the productivity of CAM application. Some tools are very simple, some require additional knowledge and skills. This is an introduction post, it gives an overview of the available tools. Please note that this post describes the automation tools that are likely to be covered in the blog later. In opinion of the author, the described tools can be used in most cases. There can be other automation methods not included here. Detailed information about each method will be added with the next posts. PRT templates These are based on a PRT template file, the one that is used for …

Improve drafting, part 3: Reuse drawing objects

This entry is part 3 of 3 in the series Improve drafting in NX CAD

This entry is part 3 of 3 in the series Improve drafting in NX CADI personally find the name “Custom drafting symbols” a little misleading. I think it refers to a much wider variety of objects than actual symbols. Personally, I prefer defining it as “reuse library in drafting”, since you can define almost every kind of drafting object. Based on my support cases I have noticed that users are not familiar with full scope of that powerful tool. Scope of drafting symbols In brief, the following capabilities are available: Reuse of sketches, including addition of fillings, crosshatches, dimensions Reuse of tables and annotations Possibility to define existing DXF/DWG as symbol Creation of drop-down lists with value, meaning that you select or enter value when …

Dear CADroad followers, First of all we want to thank everyone for support during our absence. We received the letters asking when are we moving on with new articles. Since CADroad was involved on other project, we could not keep updating our content. From this month, we would continue sharing our knowledge and we are coming up with a new set of articles. Thank you for keeping in touch and looking forward for your comments regarding new materials. Alexander and Maxim

Become a CAD user in 30 minutes with Free CAD

CAD software is simple and does not require much effort to start with basic modeling. In this article I will explain the basic principles of CAD modeling and will make a simple model in freeware CAD (called FreeCAD).   About free CAD software. Good news is that these days you don’t need buying CAD software license to start working with it. Simple CAD freeware would suite basic tasks and can help you getting familiar with basic modeling techniques. As soon as you feel that you need something more advanced, you can try some mid-market commercial packages. Most of them have a trial period and, if you are already a confident CAD user, this period is enough for deciding whether the software suits you. Each software has its …
