This task shows you how to simulate the material removed by
machining operations in Video mode using tool path data.
To learn more about this mode, refer to:
Note: It is also possible to simulate material removal in Video mode using NC code. See Video Mode for Material Removal Simulation Using NC Code.

More About Video Mode
The Associate Video Result to Machining Operation command after a material removal simulation using the Full Video command or Video from last saved result command, allows you to generate a CATProduct in a temporary folder specified in Tools > Options > Machining > Output > Tool Path files, NC Code output and NC Documentation Location > NC Code. Note that this CATProduct does not have an associated CGR .
An operation that has an associated Video Result CATProduct is indicated by a check-mark in the tree.
The Load Simulation Result command is available in the contextual menu of a machining operation which has an associated Video Result CATProduct. This command opens the Video Result CATProduct in a Video window for analysis of the machined stock, collision results, and so on.
The commands available in the Analysis toolbar that appears depend on the Machining products that are installed. Any icons that are "greyed out" are not available in the current context (but they will be available for other functionalities that share this toolbar).
Removing a Video Result CATProduct
An association that has been established between the generated CATProduct and the operation will be removed if the user executes the Remove Video Result contextual command from the contextual menu of the operation.
A Video Result may become incoherent if operations used in its creation are modified. Incoherent Video Results should be removed by the user.
Reduced Video simulation performance may be experienced in the when a user representation (CATProduct or CATPart) is associated to the tool. To improve Video performance, if possible, try running the Video without the user representation.
Note: Using an end mill or a face mill with a non-cutting diameter no longer poses performance problems.
Influence of Minimum Discretization Step
The Minimum Discretization Step that is set in the Machine Editor affects the quality of the Video simulation.
With a large discretization step consecutive tool points may be ignored and so some portions of the tool path may be removed during Video simulation.
In general, the greater the discretization step, the coarser the Video simulation.
Sub-elements in Hide/Show
If you select a Body (which may be in Show or Hide mode) as Stock, Design or Fixture then only sub-elements of the Body that are in Show mode will be used during material removal simulation. Hidden sub-elements will be ignored in the simulation.
Tools That Are Not Collision Checked
Boring Bars and Two Sides Chamfering tools are not collision checked in Video mode.
Video Behavior for Circular Arcs
Wherever there are arc segments in the tool path, circular arc commands are given as input for the Video simulation by default.
In this case there are no intermediate interpolated points where the Video can be stopped. Running one step of the Video will simulate machining of the arc segment.
To see the intermediate interpolated points (running one step), the 2D circular interpol check box must not be selected in the Numerical Control tab of the part operation's Machine Editor dialog box.
Tool Holder Behavior
In Video simulation, for a default V5 tool-holder assembly or a user tool representation, holder part also cuts material of stock and/or fixture.
Behavior depends on the Collision detection setting in the Tools > Options > Machining > Photo/Video tab:
Material is cut by holder due to nature of tool path and the interaction between the tool-holder assembly and the stock.

TRACUT Display Mode
During the toolpath replay before getting into the Video simulation mode, select the desired option TRACUT ON or TRACUT OFF that you want to see in the Video simulation. You cannot change the TRACUT ON/OFF selection during the Video simulation.
