-
Click Frames of Interest .
-
Select YAxis in the specification tree.
The FramesOfInterest.1 entity is created in the specification
tree under the YAxis part. |
|
-
Click
Frame Type .
-
Select FramesOfInterest.1 from the
specification tree.
The Define Plane dialog box appears: |
|
The Frame Type dialog box also appears: |
|
-
Select the Design frame type in the Frame
Type dialog box.
|
Refer to Frame Type table
for a description of each frame type. |
-
Select a plane of the YAxis product.
The compass is positioned on the plane at the selected location. |
|
-
On the Define Plane dialog box, in the
Move Origin area, select the Define origin at point or center
of face button.
A green dot appears on the selected plane, indicating the
location where the axis entity is created. |
|
-
Click the face to accept the position.
-
Rotate the compass so that the XY plane of the compass
lies on the selected plane.
-
Click OK on the Define Plane dialog
box.
The frame is created, and appears as a tag on the part. |
|
-
Repeat Steps 1 - 10 to create
frames of interest on the parts and planes shown below.
ZAxis
|
XAxis
|
CTable
|
|
|
|
For the XAxis and CTable parts, ensure that the
position of the axis is at the center of the circular area of the
parts with the XY plane of the axis residing on the part face. |
These frames of interest enable you to create a
prismatic joint between the YAxis and ZAxis parts, and create a
revolute joint between the XAxis and CTable parts. |
-
Click New Machine .
-
Click Fixed Part
,
and select the Base part from the specification tree.
-
Click Prismatic Joint .
The Joint Creation Prismatic dialog box appears. |
|
-
In the Joint Name field, enter YAxis;
select the line entity on the Base part for Line 1;
|
select the bottom edge on the YAxis part for Line
2. |
|
-
Select the bottom edge on the Base part for
Plane 1;
|
select the bottom edge on the YAxis part for
Plane 2. |
|
-
Select the Length driven check box; click
OK.
An Information message appears. |
|
-
Click OK.
-
Repeat Steps 14 - 18 to define a
prismatic joint between the Base part and the XAxis
part; call this joint XAxis.
Select the geometry as shown below. |

Defining Joints by Frames of Interest
|
-
Click Joint by Axis
.
The Axis-based Joint Creation dialog box appears. |
|
-
Enter ZAxis in the Joint name
field, and select Prismatic from the Joint type
list.
-
Select Design1 axis system of the YAxis
part as Axis 1.
-
Select Design1 axis system of the ZAxis part
as Axis 2.
-
Select the Length driven check box; click
OK.
-
Repeat Steps 20 - 24 to create a
revolute joint between the XAxis and CTable parts. Instead of
Prismatic, select Revolute for the Joint type;
select the Angle driven check box instead of Length
Driven.
|
Once this joint has been defined, you have defined all the joints
of the machine. The Mechanisms node on the specification tree
appears below, indicating that the machine kinematics definition is
complete. |
