review of the fundamental issues for structure and application in 3- axis CNC
machine has been carried out in this work. four major issues, tool path
generation, geometric position, feed rate and simulation, have been considered.
Numerous researches in the last decade have resulted in significant improvement
in these aspects. Among different evaluation measures, quality and efficiency
of machining are primarily used to study and compare these different developed
tool path generation, a varied and complex 3D shapes or Single Point
Incremental Forming(SPIF) method have hugely lead to the improved surface
quality and reduced machining time. while can be attained by moving the tool
along a correctly designed path. Various portion techniques such as the nonlinear
optimization method, which also leads to decreased machining time and reduced
investment cost, have also been studied.
of a virtual machining software for
geometric error of 3-axis machining has significantly improved machining
productivity and quality. Methods for the geometric error identification focus
on either improvement of the computational efficiency of the existing methods
or development of new methods. In addition, a portable laser measurement system
XL-80 with a dedicated software driver plays an important role to achieve a
high quality surface machining.
virtual machining system that optimizes NC programs methods for feed rate of 3-
axis machining has been improved the efficiency of cutting process. One of the
critical issues is the Complicated NURBS interpolation algorithms are performed
in real time, the large number of backtracking process may cause time –
consuming computations. Therefore, using an off-line feed rate scheduling
method for CNC machine. The essential of developed methods combine different
techniques with the curvature matching principle to identify the largest
possible cutter for finishing of a surface area.
In simulation by application, the
development of a smart virtual vertical three-axis machining center simulator method
has tremendously lead to the Dynamic toolpath movement, solid cutting
simulation, tool exchange, collision detection, and coolant effect. Various
portion techniques such as EMC2 version and the simulator of a common
commercial CAM software (Edge CAM) method, which also leads to capture pictures
in specific moments during machining processes, at the same points at different
depths, have also been studied.
