OPEN CASCADE CAM Library

OPEN CASCADE CAM Library is a specialized component providing dedicated CAM algorithms for manufacturing applications.

Overview

The Open CASCADE CAM Library SDK provides a set of dedicated algorithms allowing developers to:

• Convert arbitrary 2D curves into sequences of circular arcs and linear segments (treating 2D curves contained within edges that form planar wires/contours)
• Build planar sections of a shape (using its mesh representation)
• Offset planar sections
• Build path contours for pocketing operations
• Build geodesic curves on the surface of a shape:
  • Shortest paths between two given points
  • Isolines for given start points (seeds) and distances

Features

The Open CASCADE CAM Library enables the following operations:

Convert Contours

• Special package providing algorithms to convert contours of arbitrary 2D curve types into contours consisting only of 2D circular arcs and 2D linear segments

Compute Planar Sections

• Dedicated algorithm for computing planar sections on sets of triangular meshes

Compute Planar Outlines

• Algorithm for computing outlines (planar projections similar to HLR) of sets of triangular meshes

Compute Planar Offsets

• 2D offset algorithm capable of building offsets of polygonal contours (contours composed of linear segments)
• Supports outer offsets (expand-type polygons), inner offsets (shrink-type polygons), or both simultaneously

Compute Paths for Pocketing Operations

• Dedicated algorithm for computing tool paths for pocketing operations on planes
• Current implementation provides an internal pocketing algorithm that calculates sets of offset contours placed in pocket border interiors

Geodesic Algorithm

• Algorithm for building geodesic curves implemented in a dedicated class
• Works on discrete (triangulated) models represented by triangulations of input shape faces
• Process begins with building a precise distance field on triangulations (inaccuracy defined only by roundoff errors)
• Enables computation of shortest paths and isolines

Benefits

• Critical for CAM applications requiring efficient, ready-to-use computational algorithms
• Seamless integration of CAM functionality with CAD modules written with Open CASCADE Technology
• Combined elementary algorithms solve complex CAM tasks
• Computation results easily convertible to formats needed by various machines
• Backward compatibility of results with OCCT modeling functionality, enabling further processing using OCCT algorithms
