Branch Types - Turning

Below are some notes on the various types of branch that can appear in the Fixture and Machine trees for Lathes. The illustrations of the branches are typical examples (so 'Z Axis' represents all axes, for example).

Notes

Machine

Double-clicking this branch opens the Machine Parameters dialog for entering or editing the machine's 'physical' configuration information, such as the toolchange positions.

Machine

 

There are X,Y, and Z and A,B and C axes. They have properties such as Origin (an XYZ position) and Min and Max (movement). Can contain further branches (axes, turrets and so on) for the items that are mounted on the axis.

Indexing Turret

Machine

 

Properties include Number of Stations and Axis (X, Y and Z values). Axis sets the direction of the indexing vector that the turret rotates around. Set X, Y, and Z to the end coordinates of the vector, as in this indexing around Z example  or this cranked indexing example. Note the station numbers increase moving anti-clockwise when looking along the vector from the end point towards 0,0,0. For more details, including indexing on Z, X and Y examples, see Setting Turret Indexing Vectors.

ATC Turret

Only has a name property.

Fixture

Graphic. Can be your own custom graphic, or the automatically created 'parametric' graphic.

There are different parametric graphic types, such as Chuck Graphic and Turret Graphic. This reflects the different properties required - Chuck Graphics need a Jaws Number property, for example.

Graphics have an Origin property, so that you can re-position the graphic.

Graphics also have a Type property which can be Fixture, Guard, Base, Turret or Spindle. This allows the graphics to be shown or hidden in groups, using the Display toolbar buttons; there is a button to show or hide each type.

Machine

Only has a name property.

Fixture

Use this as a container for other branches. Part of the machine tool might be represented by a custom graphic for visualisation and a paremetric graphic for simulation. Place these graphics into a folder to group them - you could move the group by moving the folder, for example.

Folders have a Name property (editing this property is how you change the name).

Machine

&

Fixture

Only has a Name property. Can be part of the machine tool setup in the Machine Tree, or in the Fixtures Tree, to be available for use on a job-by-job basis. Always created with a Chuck Graphics branch, which sets the properties of the chuck (number of jaws and so on).
