Advanced Manufacturing

How do we at Forge Model Works use Advanced Manufacturing make a difference in the modelling world?  A good question…

Our experience of different manufacturing technologies means that we can utilise the most appropriate manufacturing process for each component. The “Advanced” aspect of our manufacturing means that we take full advantage of automated or computer driven equipment to produce components in the most efficient way.

As we discussed in our DESIGN page, the component information created in our CAD system can be used to seamlessly drive manufacturing processes. This reduces error, improves quality and improves efficiency. Here are some important examples:

  • Machining: CNC (Computer Numerical Control) usually involves cutting out a 3 dimensional component from a plastic or metal solid workpiece. We create a 3D model of the finished product (as well as a traditional drawing), this is then used directly to program the toolpaths on the machine tool.  This method of information transfer conveys the finished component design clearly and quickly, ensuring greater accuracy and speed of production.

  • Turning: is essentially revolving a 2 dimensional profile around a rotating workpiece.  As with machining we take a 2 dimensional profile and use that as the basis for the turning process.  With both turning and machining the data used for programming can also be easily used to check compatibility with available cutting tools, tool shapes and clearances.

  • Laser cutting: For laser cutting we generate a 2 dimensional flat profile, for wood, metal or plastic, and use this to set up a toolpath for the laser to follow and cut the material. The component profiles are also used to ‘nest’ the components on a virtual sheet of material and so optimise the utilisation of the material.

  • 3D printing: There are two useful types of  3D printing:
    Fused Deposition Modelling (FDM) where objects are built up layer by layer from extruded plastic.  We do use that technology but prefer the better definition and surface finish of stereolithography.

Stereolithography (SLA)

  • which cures layer of liquid resin using a laser.  The system we use can print layers down to 0.025mm thickness (1 thousandth of an inch) which creates highly detailed models with effectively a smooth finish.

But isn’t all this technology cheating on the modelling process? Well, the choice is always yours; you can utilise products and services in the way that best works for you but for ease, accuracy, and especially batch production of models, advanced manufacturing has real benefits.
