The Benefits of Modular CAD/CAM systems
Modular CAD/CAM software systems allow different software functionalities to be available independently of one another.Many times CNC manufacturing businesses seek out CNC programming software only to find that they end up paying for CAM technology that they really don't need, along with maintenance that they will never use. A simple solution to this is the development of modular CAD/CAM software, which allows different software functionalities to be available independently of one another. 
Giving CNC businesses the ability to add on to a CAD/CAM product as needed for upgrade costs in functionality is a better way to help shops grow as they learn CAM technology and employ it into their operation. For example, a shop that has a CNC router may start off with a complete 2-axis CAD/CAM system that allows them to create 2.5 axis toolpath and G-code programs for a router. The same company may then acquire a 3-axis CNC machine down the road, and would be able to add on to the software and upgrade to the next level, at very low cost, in order to take advantage of machining technology for 3-axis, and so on.
For small shops, this makes more sense than the alternative, which is to have to pay more money for more technology, which some shops simply wouldn't use until the right job came along.
The bottom line is that modular type CAD/CAM products give smaller shops with tighter budgets the opportunity to grow by starting off with simpler software packages that cost less. They can upgrade software functionality as they need it, which is a great benefit for shops that are getting into making molds.
Shops can save money by upgrading CAD/CAM software to add higher level toopaths and programming functionality, such as a multi-axis package, which can include seven surface-based toolpaths that increases the user’s ability to control where and how material is removed.
Since it doesn’t cost as much for an upgrade as it would to buy an entirely new package, this is recommended as the better route for shops to take. Starting with a simple 2-axis product and gaining the skill set to be utilized with the higher end features that a multi-axis package offers when warranted.
Multi-axis is just that, not only does it offer more toolpath options, it also supports 4- and 5-axis output. As your parts get more complicated to machine, it usually means you are adding a 4th or 5th axis to eliminate setup time or just to have the ability to cut the parts according to the design.
Suppliers that offer 4-and 5-axis upgrades are able to support table-table, head-table and head-head machine configurations, giving CNC businesses a more affordable path to acquire this type of technology.
Other modules offer CNC machining capabilities such as lathe, part nesting and sheet optimizing as well as artistic CAD/CAM, which allows the user to take a picture and turn it into a relief model or profile geometry that can then be machined.
The point is that these modules can be purchased separately, so businesses can introduce these functions into their shops as the need arises. Shops can save money and add technology as they grow.

Mould manufacturing is a complicated process consisting of many stages that cover all the departments of a manufacturing company, from design and prototyping to analysis and metal machining. This industry is a showcase one when discussing the benefits of modular CAD/CAM solutions stated in the article above. A manufacturer might decide, which software modules can be acquired for each of the mould making stages - sometimes there is already a solution which suits well for performing some tasks, or there has been an investment made into a certain technology, and a new software module is required.
Hexagon Production Software is a software developing company that develops revolutionary software suites for different kinds of manufacturing, following the module approach. The company's message about it is that software is growing with the manufacturer's experience and enhancement of the company's processes. Obtaining a new machine, starting a new process or hiring an analyst - everything like this may become a reason to obtain a new module for the software suite that is already familiar and successful.
The same happens in mould making industry with VISI CAD/CAM software solution. It offers a full coverage of all the operations in design, analysis, quality control and metal fabrication sections of a manufacturing company. Starting from a small mould shop working with the existing CAD drawings, a manufacturer might grow and purchase software modules for 3D modelling, mill turn applications and wire EDM, with further enhancements towards research and development, gaining modules for plastic flow analysis, mould analysis and even reverse engineering. All the VISI modules are integrated into each other and follow the same user experience principles, that shorten the learning curve for new users and improves the skills of the existing ones.
