Class A Surfacing
Class 'A' surface refers to those surfaces which are visible in a product. This service is primarily used in the automotive environment and increasingly in consumer goods. It is a requirement where aesthetics have a significant contribution. E.g. the exterior of automobiles are deemed Class-'A'.
Why would you require Class 'A' surfacing. We all know that today's products are not only designed considering the functionality but special consideration is given to their form and aesthetics which is crucial in the perception and reality of a quality product to the consumer. This quality is only possible with high-class finish and good forms. This is the reason why in design industries, Class 'A' surface are given more importance.
DEVELOPMENT OF COCK-PIT
This was complete development of Cockpit, Front facia rear bumper, hood, side skirt. Responsible for Class A surfacing from input is given as scan data, Master Sections and sketch provided by styling and Engineering department. Understanding styling and engineering requirements parts. (Environment geometry).We use scan data as reference converted it to class A surface considering all the A Class criteria and later made changes in it according to the new sketch provided to us. And at the same time keeping in mind the manufacturing feasibility.
Class A Consideration
∗ Smooth Curvature comb
∗ Maintaining smooth styling intended Tangent lines or feature lines
∗ Maintained Position 0.001mm, Tangent 1-4 degree, curvature 0.01
∗ Maintaining smooth Highlight, Smooth Curvature comb plot & performing Draft analysis.
HOOD, FRONT FACIA, SIDE SKIRT
The input is given as scan data and sketch provided by styling department. Understanding styling and engineering requirements, verbal instructions, sections requirements and feasibility with engineering parts.
Converted referenced scan data to class A surface considering all the A Class criteria and later made changes in it according to the new sketch/rendering provided.
Quality check performed on sharp model like Highlight plot, section comb
