1462 HEIDENHAIN Technical Manual iTNC 530 HSCI
Example Example of modeling a simple fixture without variable, which consists of three
individual bodies (CMOs).
To model a new fixture, proceed as follows:
Start the KinematicsDesign PC tool.
Select File / New... to create a new file.
Select:
Fixture to model a permanent fixture without variable input parameters for
the user (*.cfx file), or
Fixture template to model a variable fixture (*.cft), which will be given its
final shape with the FixtureWizard tool.
Enter any file name for the fixture.
Design the desired fixture by inserting collision-monitored objects (CMOs)
and the required transformations between the individual objects. The
generation of the simple fixture shown above is described below in steps 1
to 5.
KinematicsDesign saves the fixture as a *.cfx or *.cft file, depending on the
selection.
Fixture templates *.cft and individual fixtures *.cfx enable the user to enter
variable input parameters. Keep the following differences in mind for
modeling:
Design a fixture in the form of a fixture template *.cft in such a way that it
can be changed with the FixtureWizard. The user then uses the
FixtureWizard to adapt the incomplete fixture template to the actual fixture.
This gives the user the possibility to change, for example, the length of the
fixture or the jaw height, depending on the application (i.e. the real fixture).
Design a readily usable fixture *.cfx, and give the user the possibility to
change parameters of the otherwise complete fixture, which might not be
constant quantities (such as the jaw distance) when ascertaining the
position and orientation of the fixture. You enter these changes without
using the FixtureWizard. During the process of ascertaining the position and
orientation, the user is guided through a menu, in which the editable
parameters can be defined.
For information on operating the FixtureWizard, refer to Chapter 11.3 – "Fixture
Monitoring" of the User's Manual for the iTNC 530.
