Turret Station Editor on the Manufacturing Program

On a Manufacturing program:

You can add tools/tool assemblies present in the Resource list to Turret Stations. You can also view the tools and their stations for a specific turret using a Turret Station editor.

When a kinematic Multi-slide lathe machine is assigned to a Part operation, you can specify which turret is to be used in the Manufacturing Program using Turret Station Editor.

Turret Station Editor allows you to select Tools /Tool Assemblies from the Resource List and assign them to a specific station on the Turret.

� Before Retract macro (Turning operations) – Retract motion should be define at the

operation level � End

Define which turret drive the other one in a feedrate point of view

How to Create Synchronizations (1/2)

To Optimize machining time, it is necessary to make machining on the different turrets at the same time. To control the starting point or the end point of a machining operation, you must create synchronization between two operations.

The pasted operation which is cut or copied can not synchronized.

How to Create Synchronizations (2/2)

Synchronizations are not visible in the ProcessList (PPR tree). They are visible only in the Gantt chart view (see next Lesson for all info concerning Gantt Chart)

In the Gantt Chart view, the Synchronization are visualized by a line with a number and a point in red color

To delete a synchronization : use contextual menu on the line + deleteLine allows to put time correlation between the two machining operations (A)The number is the number of the synchronization (B)The Point indicate which turret is the master (C)

Gantt Chart (1/5)

Gantt Chart allows to visualize the distribution of the machining operations in time between the various turrets

Operations of all programs are displayed as a function of timeDirect graphical access to synchronizations & operations � (Definition, Replay, etc)

Unused time information by ProgramOperation status and times are recomputed when you open Gantt chart to take into account synchronizations and Master turret

It provides overview of all programs for time optimization

Gantt Chart (4/5)

‘Total time’ of operations and ‘Unused time’ are used for computing the Part Operation overall time.

For machining activities, total time is the ‘Calculated cycle time’ automatically set when computing the tool path For non machining activities (Tool Change, PP Instruction and Machine Rotation), total time is the value entered in ‘Specified cycle time’ that is used.

Time Computation:During synchronization definition, we can set a turret as Master. Then this turret drives spindle speed for time computation of machining operations on all other turrets As long as there is no new synchronization order with a change in the definition of the master, this turret remains master and the operations on it drive the othersIf turrets works together without definition of master, a warning message is displayed in the diagnostic window (NC Gantt Chart) and computation of real time won't go any further

About Time Based Replay

Time-based Replay simulates all the activities as a function of timefrom the absolute start time of the Part Operationfrom the start time of a selected operation : all simultaneous and following operations are replayed

Time based replay allows checking Program sequence and Synchronization influences. It also allows checking potential collisions between tools.

If referenced tooling is shared by at least one simultaneous operation of another turret, you must duplicate this tooling in order to view all simultaneous tooling positions.

About Time Based Video

Time based video allows you to simulate multi-turret and multi-spindle scenarios with synchronized operations as defined in the Machining Gantt viewer.

You can set the video simulation time step for customized visualization.

The video functionalities such as save video result as CATProduct, collision lists, video analysis commands are available in time based video simulation.

Time based video is available for multi-turret machines.

Counter Spindle Output

You can compute the tool tip points for turning operations that are defined on the counter spindle with respect to counter spindle part axis system rather than the main spindle part axis system.

You need to select ‘Use Spindle Axis System according to the Spindle involved on the Machining Operation’checkbox in the Option tab of the Part Operation. When you select this checkbox the tool tip points will be computed based on the spindle and its axis system that you have set.If the checkbox is not checked then the main spindle axis is taken into account.

You can set a counter spindle for a particular machining operation through Spindle name in Strategy tab. For this, you need to assign multiple spindles in machine editor.

Machine Axis change is not required even if multi-spindle are used.
