VX CAD/CAM integration has allowed Ramix and its sister company Romit to reduce outsourcing of CAD and CAM tasks.

Shortcomings in Ramix’s existing CAD and CAM systems hindered the design of impellers and moulds, which Romit was responsible for machining.

This led to the outsourcing of the design work.

Auke Sjoerd Tolsma, director of Ramix-Romit, said: ‘We were amazed at how well the VX tools worked.

‘Customers would send difficult 2D drawings and it was easy to quickly construct 3D parts and get them on the mill.

‘This opened the door to modelling and machining impellers.

‘Romit often gets no more than a table of coordinates in radials for the complex 3D form of an impeller.

‘It will use a spreadsheet to calculate the coordinates and import them into VX where the powerful wireframe and surface modelling tools take over.

‘It takes us more time to import and convert the data in our spreadsheet than it does to model an impeller.’ A VX CAM uses up to five-axis milling to machine the impellers.

Tolsma added: ‘After the introduction of VX CAD/CAM, we have increased our machining hourly rate by more than 20 per cent.’ Ramix rarely needs 2D drawings: it simply sends VX CAD models directly to VX CAM.

Tolsma added: ‘After building up the mould, no time-consuming drafting is wasted before parts can go into production.

‘The parts list is filled-in using the assembly manager.

‘In the shop, no time is wasted on punching in the dimensions of pockets or coordinates of holes into the machine.

‘Milling the parts with VX CAM saved us several days of machining time.’ VX’s Open Shape / Hybrid modelling is another important contribution to Ramix.

Tolsma said: ‘Often we receive bad IGES files where surfaces don’t connect, overlap, or are missing completely.

‘Despite these errors, we quickly make good working mould parts without healing the imported file to a solid model.

‘We even help customers improve the design during the construction process.’ All of VX’s inspection tools work well with solids and open surface models, allowing them to inspect cooling channel clearances.

VX Quickmill doesn’t differentiate between surfaces and solids, making it easy to identify the regions that were changed by the customer for re-machining.

Before any metal is cut, VX can simulate the movements of complex moulds.

This shows the customer how the mould construction will be realised.

Ramix uses the powerful freeform tools of VX every day to calculate and design parting lines and faces for complex moulds.
