## Compensation G41/G42 – Alphacam #46

G41 / G42 Compensation We said a few words about tool radius compensation. What is it and how it works. But there is one quite important issue. What is the difference between G41 compensation and G42 compensation? Compensation G41 is a left-sided compensation. This means that the tool is located on the left side of…

## Compensation and Toolpath – Alphacam #45

Compensation and How the toolpath is generated in CAM systems? Now, it’s worth taking a moment to understand how the tool path is generated by the CAM system. And this is not about the CAM system algorithms, but more about what is the basis for generating the tool path on the basis of which the…

## Update Tool Paths – Alphacam #38

Update Tool Path – Alphacam YouTube: https://youtu.be/ewTbynOJQIA Previously, I showed you how to move the geometry to the origin of the coordinate system. Of course, we can use the move function not only when we want to move the geometry to the origin of the coordinate system. Sometimes you just have to move the geometries…

## Contour machining part 11 – Remove from operation – Alphacam #31

Remove from operation – Alphacam YouTube: https://youtu.be/RS34kL0ryf4 In the previous post I showed how to add geometry to the operation, for example in a situation where we did not select all geometries and confirmed the choice or when we just added a geometry and we do not want to create another operation for this one…

## Contour machining part 10 – Add Geometries – Alphacam #30

Add Geometries – Alphacam YouTube: https://youtu.be/g-2wUrql4Tg When preparing the contour machining, we do not have to create a separate strategy for each contour that we want to work with. If we plan to machine several contours at the same depth, we can do it in one operation. Sometimes, when selecting geometry, we will not select…

## Contour machining part 9 – Spiral stock removal – Alphacam #29

Spiral stock removal – Alphacam YouTube: https://youtu.be/-atF9rcMr7A In one of the previous lessons, we talked about the parameter Helical Interpolation, which allowed to prepare spiral milling in the Z axis. An interesting parameter is the Spiral stock removal parameter, which allows spiral removal of material in XY axes. After setting parameters such as in the…

## Contour machining part 8 – Initial Stock – Alphacam #28

Initial Stock– Alphacam YouTube: https://youtu.be/KJxvCJVJqrs The next parameter in the Machining Data tab is the Initial Stock parameter. This is the finishing allowance that has remained after the previous machining. The pre-field of this parameter is blanked. To activate this, in the Stock Removal section, we must specify Number of Cuts for machining this allowance….

## Contour machining part 7 – Stock to be Left – Alphacam #27

Contour machining part 7 – Stock to be left YouTube: https://youtu.be/lc46EV8UnjM Now we will move to the next tab in contour machining – Machining Data. The first parameter is Stock to be Left. This is the value of the allowance in XY axes to be left after this machining. So the allowance on the walls….

## Contour machining part 6 – Helical Interpolation – Alphacam #26

Helical Interpolation in Alphacam YouTube: https://youtu.be/8okdsE8gw5s Helical interpolation in Alphacam is an option which allows us prepare helical machining, found under the names milling on a helix or spiral milling. A very nice way to machine contours. It allows for a very good finish of the machined wall. To enable machining on a helix, in…

## Contour machining part 5 – Depths of Cut – Alphacam #25

Contour machining part 5 – Depths of Cut – Alphacam YouTube: https://youtu.be/MGtn6NwjGZI At this point, we have prepared the machining in 10 equal passes I Z axis. In most cases, equal passes will be a good solution, but sometimes it is worth specify the depth of the first and last pass. We can do this…
