How to Use This Course
To assist in the presentation and learning process, the course has been structured
as follows:
Lessons:
Lessons provide the key concepts, methodologies, and basic skill practice
exercises. The goal of each lesson is to present the necessary knowledge and skills
to master a basic level of understanding for a given topic.
Master Exercises:
Master Exercises provides a project where an industry type parts are used to assist
you in applying the key knowledge and skills acquired in the individual lessons as
they apply to real world scenarios. The master exercises also highlight the process
and steps for completing industry parts.
Recap Exercises:
Recap Exercises are provided along with Master Exercise Steps.
Note: According to preference, the Master Exercise
individual steps will be completed after an individual lesson
containing its key concepts.

About Surface Machining
It is of paramount importance that the tool paths are correct and that the
tool does not gouge the part or leave material in unexpected portions.
Surface Machining offers the technology to generate Tool path for
3-Axis Machining Operations. This helps you to upgrade from 2
and 2.5-Axis operations.
The key issues in milling of complex shapes are:
1) Accuracy and finish of the part
2) The machine time required to complete the operation
3) The time spent for preparing and validating tool paths for
machining.
A full set of 3-Axis milling and drilling operations for accurate
tool path definition, including support of High Speed Milling
technology.
Automated detection and reworking of unmachined areas during
roughing or finishing.
Flexible management of tools stored in file-based tool catalogs
or in external tool databases.
Tool path verification by material removal simulation.
Associativity with CATIA design parts for efficient Change
Management.
CATIA SurfaceMachining features include:
Surface Machining is very much useful for manufacturing of Moulds,
Dies and Prototypes in all types of industry.
