|This task shows you how to insert a isoparametric machining
operation into the program.
Isoparametric machining is an operation which allows you to select strips of faces and
machine along their isoparametrics.
Click Isoparametric machining
then select the geometry to be machined
A number of parameters are available in the machining strategy tab:
tool to use (the tools that
can be used with this type of operation are
Maximum allowed distance between the theoretical and computed tool path.
Ensure linearity between points that are far apart.
Maximum angle between two consecutive points that the machine is able to
here for information about the 3/5-Axis Converter option.
Defines how the distance between two consecutive paths is to be computed.
The choice of one type activates the corresponding parameter.
Those rules also applies when Skip path or Startextension/End extension are active.
You may also choose to skip (not machine) the first or last path or both
Specifies the length of an additional machined area located before the
first path on part.
Specifies the length of an additional machined area located after the
last path on part.
Define the tool axis guidance mode:
You can specify the following geometry:
||Selection of triangular faces is allowed, but may give
unexpected result in terms of tool path (see examples below).
It can be performed on check and part elements with the tool
To save computation time you should use tool assembly only
if the geometry to be checked
Isoparametric Machining: Collision Checking - Part parameters
To activate collision checking on part elements, you must select the
Active check box.
Collision checking on part elements is not useful in the following cases:
Maximum precision error to be accepted in the respect of the part (or check) with its thickness.
Maximum cutter interference with the part (or check) during macro motions.
Isoparameteric Machining: Collision Checking - Check Parameters
The parameters involved for check elements (such as fixtures) are:
Check (or Fixture) Accuracy:
Allowed gouging: maximum cutter interference with the fixture
during "linking passes"
Select this option to optimize air cuts due to collision with the check.
