PART A
List out the benefits of the CAD/CAM.
Answer
The primary benefits of CAD/CAM include increased design productivity, improved product quality through better analysis and simulation, shorter lead times for product development, and enhanced manufacturing accuracy through automated toolpath generation.
What is the difference between parametric and non parametric form?
Answer
In parametric modeling, geometry is defined by parameters and constraints, allowing the shape to update automatically when dimensions are changed. In non-parametric modeling, the geometry is defined by fixed coordinates or explicit values, meaning changes require manual editing of the underlying points or lines without associative intelligence.
