End Milling

End Milling |
Remove any material perpendicular to a face or contour between the finished part and rough part by extending it to the horizontal limits of the rough part and observing any possible islands that may be found.
TopSolid'Cam recommends a number of Z passes based on the material to remove and the cutting conditions of the called tool.
End milling includes facing or pocketing operations.
The face designed by the operator is automatically extended to the first limits encountered by the rough part.
If islands are present in the middle of the face to face, the algorithm manages their potential juxtaposition, which prevents passing the tool. The algorithm also manages corners of which the minimum radius is less than the tool radius. In these two cases, TopSolid'Cam generates residual material that will be automatically recognized by remilling operations.
When configuring milling settings in dialog boxes, the actual machinable area is viewed by interactive hatching.
Several plunge modes are available, based on the tool selected by the operator. In the case of a full material, quick feed rate or feed rate vertical plunge, the user can define a plunge point or use the point proposed by TopSolid'Cam.
The expanded facing 
allows to machine several faces at a same altitude even if they are separate by a gap (Without any stock TopSolid keeps trying to extend to see if we can find stock left!) :

It is possible to request integrated contouring (i.e. with compensation G41 / G42) to finish the sides.
Open pocketing + integrated contouring with " BOOST " strategy |
Pocketing + integrated contouring with " successive contouring " strategy |
In contrast to a conventional end machining strategy, in the integrated contouring of the "BOOST" the feed rate is automatically reduced on the corner arcs to preserve the amount of material to be removed.
|
By default, the feed rate remains at the work feed rate in the corners of the integrated contour. To reduce the speed in the corners, we have to set the speed change parameters in the corners of the "HSM" tab.

From the 2D/3D menu or using the mouse (select a face with the right mouse button), select the end milling.
A toolbar appears on the left of the screen, along with a label in the graphic area.
You can then modify values by
By selecting the value to modify in the label. The label is the table shown in the image in the top right corner. All label values are fields available from one of the icons in the left section. These values are placed on the label for quicker access.
By selecting the values in the graphic area or by pulling the arrows (the 2 fields have a value of 0.5 in the top image, above the hatching area). As with the values of the labels, these fields are present in one of the left section icons. These values are placed in the graphic area for quicker access.
By opening one of the left section icons.

Select Favorite
Instead of modifying n values, this option allows you to restore (or save) values that have already been entered.

Select the tool to use
By default, if the previous operation tool can be used, it is reused for this operation (the name of the tool appears in the graphic area next to
If the previous tool is not suitable or if this is the first operation, you must select a tool to validate the operation (

Define Cutting Conditions for Operation
Use this icon to modify the cutting conditions of the current operation.

Define or Add Geometries to Machine
Use this icon to select (or remove) machinable geometries. This geometry is automatically added, by first selecting the geometry and right-clicking "End Milling". You do not have to access the icon to do this.
Define Milling Boundaries
You can also apply trims (XYZ or contour) to the current operation.

Define All Milling Settings
Each milling has specific settings. Use this icon to access all settings (such as stocks to leave, altitudes, plunge modes, milling modes, etc.)

|
Define ISO File Settings
Use this icon to define which comment to use for the ISO code or to decide which inclined plane matrices to use.
|
|
Define colinear axis
This icon is available only if the current machine has colinear axis.With this icon it will then be possible to choose the axis drives by the operation.We also can choose the Z value of the fix axis.
|
|
Allow us to add one or more axis on the current machining
For example on 4 and 5 axis machine, to have the possibility of doing radial or axial operations. |

Define Operation Properties
Use this icon to define whether you would like to update the stock or calculate the result later.

Editing Update
Each time a setting is changed (such as the axial depth), all calculations for updating the hatching area and the trajectory are triggered. The setting change may take a few moments. In several cases, settings must be modified before updating the calculations. For this, press this icon. In the case, the hatching area and trajectory (for example) are not recalculated before pressing this icon again.
