Coordinate System

Once part geometry is loaded, user can set the cutting direction.  This orients the Machine Coordinate System for Turning to have the part aligned in the same way as it would be fixtured on the machine tool for cutting. The stock geometry and machine tool definition will be defined based on the orientation of the machine tool coordinate system.

This dialog offers a convenient way of aligning the Machine Coordinate System (MCS).

tog_minusThe Machine Coordinate System (MCS)

The Machine Coordinate System (MCS) is displayed as a triad with Blue line representing the Z-axis, Red representing X-axis and Green representing the Y-axis. The WCS is displayed the same way as MCS and is located at the origin. The lengths of the WCS arrows are shorter when compared to MCS.

tog_minusAlign to

This aligns the MCS orientation.  Select from the following:

World Coordinate System  
Setting the MCS to the WCS. In this case MCS and WCS would have the same coordinate location.

 

Active View Construction Plane  
Setting the MCS to the orientation of the active viewport of the construction Plane.

 

Geometry:

Part Surface  
User can select a point on a surface determine the alignment of MCS.

 

Geometry:

Planar Curve  
User can select a planar curve (2D sketch) to determine the alignment of MCS.

 
tog_minusSet Orientation Parallel to

Allows you to set the Machine Coordinate System parallel to the World X Y or Z co-ordinate axis.

•World X  
Orients the Z axis of MCS parallel to World X axis.

•World Y  
Orients the Z axis of MCS parallel to World Y axis.

•World Z  
Orients the Z axis of MCS parallel to World Z axis.

tog_minusRotate about

Allows you to rotate the Machine Coordinate System in X Y Z coordinate axis by any angle specified under Spin Angle.

Specify Spin Angle and click the axis to rotate about. Clicking the same coordinate axis button multiple times rotates by the specified angle incrementally. For example if you set the Spin Angle = 90 and click X Axis button 2 times, the MCS is rotated about X coordinate axis by 180 degrees.
tog_minusCoordinate System Origin

This translates the MCS origin to the desired location. This can be set to any location on the part geometry.
tog_minusReset to Original

Resets MCS orientation to current MCS orientation.
