Siemens Digital Industries Software solutions help Shikun Enterprise streamline complex manufacturing processes and increase productivity. On-Demand Webinar 41 minutes.
Large part program files can be input or output directly to data server storage. The Machining Simulation for Workforce Development software is a perfect solution for safe and effective machine tool training. The realistic simulation software can now be operated as 5-axis and 3-axis mills or a 2-axis lathe. Self-explanatory menus and 3D graphic simulations guide the user through the programming, producing highly efficient results even for complex machining processes.
Want to get more out of your operations? A lot of other kinds of CNC Software are available to help facilitate this process such as:. There are a variety of different markets for CAD. The most common programs in the mechanical CAD market include :. The first part I ever did was drawn in Rhino 3D, and was done for a chuck backplate project on my old manual lathe. Choose your CAD package very carefully. This is likely to be the CNC Software you have to spend the most time with.
I started with the trial version which is limited to 25 saves or some such. I ran through their two basic tutorials in t he trial version, and when I got my official copy, I was able to whip out the chuck backplate 3 views in about an hour. I figured this was not too bad all things considered! This is an important distinction to understand well.
A parametric modeler uses constraints or parameters, hence the name to determine the dimensions and relative orientation of the objects being modelled. Explicit modeling maintains no history of parameters. Each new object can be created on its own. What are the pros and cons? The distinction between the two is quite a hot topic in the CAD world today. For a long time parametric was thought to be the highest productivity.
Lately, people are beginning to question that assumption and look more closely at explicit modeling. In all likelihood, the two will meet somewhere in the middle with parametric CAD software developing explicit modeling features and vice versa.
I like to think about it like this. Parametric CAD excels in two areas:. Imagine having to create models for all the different sizes of socket headed cap screws, for example. With parametric, you create one model that is parameterized according to the standard dimensions of a SHCS, and you are done.
Suppose you are involved in a manufacturing process that is spread out, perhaps across several companies. Because communication is not great over such long channels, everything is done via change orders, and there are lots of change orders.
A properly created parameteric model makes it easy to respond to change orders. As you can see, parametric is all about creating lots of versions of a single model. When that is the challenge, you will have maximum productivity with a parametric CAD package. If you know what you want, it is much faster to do it via explicit modeling.
Setting up all the different parameters in parametric takes a lot of extra effort. In addition, it is much easier to learn explicit modeling packages. Parametric thinking is not particularly natural and it takes some training and experience before it becomes second nature.
I have a hard time getting excited about 2D packages in this day and age. The issue to consider if you have to do a lot of 2D drawings, perhaps due to organizational standards, is whether your chosen package is good at it or not.
CAD is no exception. Both are quite powerful, and quite new. They have free trial packages that will enable you to try them before buying. The CAM software takes a drawing from CAD and produces g-codes which you may feed into your machine control software to drive the machine.
There are a variety of programs available in this category including:. And many other s. In it, we take you step by step through making the same part with 2 different inexpensive packages—MeshCAM and CamBam. How should you evaluate a CAM package? Choose the most popular one? Choose the most powerful? I prefer to ask a set of questions designed to get a balanced view of which package will be right for your needs. Evaluating a CAM package to find which one is right for you is a serious business worth investing some effort into.
Avoid the canned demos because they always look slicker than they really are. If so, make sure the CAM package works well with that format. See my article on postprocessors for more on the considerations for postprocessors and buying CAM.
When shopping for CAM, I made it a point to take a look at the user communities for each package and check out what parts had been made with the different programs. Let me show some of the parts and projects I came across in my journeys:. There were many more than this, but these were some of my favorites from my original search you can see my interest in picking up CNC was motorsports related!
I think many machinists would be pleased and proud to call any of these projects their own. They obviously reflect a great deal of talent on the part of their creators.
