How to Create Synchronizations (1/2)
Student Notes:
Copyright DASSAULT SYSTEMES
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. Create synchronization between two operations Click ‘Creates a synchronization’ icon Select an operation of a turret Select an operation of an other turret Select where in the operations, you want to put the synchronization Start After Approach macro (Turning operations) – Approach motion should be define at the operation level 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
The pasted operation which is cut or copied can not synchronized.

Multi-Slide Lathe Machining Student Notes:
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 + delete Line 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 (4/5)
Student Notes:
Copyright DASSAULT SYSTEMES
‘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 others If 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
Student Notes:
Time based replay allows checking Program sequence and Synchronization influences. It also allows checking potential collisions between tools. Time-based Replay simulates all the activities as a function of time from the absolute start time of the Part Operation from the start time of a selected operation : all simultaneous and following operations are replayed
Copyright DASSAULT SYSTEMES
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.

Counter Spindle Output
Student Notes:
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.
Copyright DASSAULT SYSTEMES
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.
