The ship propeller has long been an essential and indispensable part of the ship. That is a necessary part of the loss of the vessel will not be able to operate most efficiently.
About the specimen (the ship propeller) to be processed
Datum Limited, headquartered in Derby, UK, is an engineering company with roots in the casting industry with a Pattern & Tooling offering that is an essential part of the company’s business activities. Datum occupies the majority of the market as a supplier of Phenolic GRPh / GRP products.
Datum’s tool and modelling workshop operates on an area of 12,000 sq ft and offers comprehensive CAD / CAM solutions, from data collection and processing to CNC machining operations. Datum also offers traditional prototypes and models with a highly skilled workforce made of wood, metal, plastic and polystyrene materials. It has a long experience with the machine impeller Molding Product—ship & Pumps. (ship propeller)
Datum was recently asked to produce a new model for a turbine in 1950 with very little information in the form of a sketchy drawing without propeller parts and a very worn casting that has been around for decades. Submerged underwater, and the surface of the Turbine was extensively eroded.
From the scanned data from GOM’s ATOS Compact Scan 5M blue light 3D scanner system, it was discovered that the Molded Turbine was oval in shape and did not have a pump blade of any size and shape. The same format. The original part has been produced by hand, and the prototype is shaped and partially engraved on the drawing.
People knew they used the efficiency of the impeller very well in the 1950s, but balance and noise from the shaft part could not meet today’s requirements.
After decades of immersion in water, the inferior surface of the moulded product turns into 3D scan data and needs smoothing. Datum Director Paul Nelson: “We chose one of the best conditional blade blades and used this data to create 3D CAD files and insert smooth surfaces onto the 3D scanned data. worn out “. Using the 3D scanned image of the Turbine, we create a concentric symmetrical shape, with the same number of blades but in the correct centre position. Then design the mould and mould it to ensure all the resulting core parts have the right slots, add material for machining and draft before sending it to the customer for approval.
“The core line worked very smoothly, which were positioned perfectly together, precisely matched the drum groove, and did the 3D CAD model’s flow analysis to ensure the sprue and track. Design precisely before casting. The result is the excellent new blade casting product with complete precision; when the moulded impeller part is finished and machined, begins to work, show smooth performance, and much quieter than old casting parts, “confirmed Paul Nelson.
