In the case of simple 2D Contour processing, the one we have in the example is difficult to show the use of this option, but it should looks like this. The Lift Height option is responsible for this. the tool will move at the bottom of the pocket (of course where there is no material), but it can generate unnecessary heating of the tool and material. If we keep the tool in the bottom, then the move to the next area will take place at the depth level at which the machining is performed in the current operation, i.e.
The tool will not retract if the distance between next areas is less than that specified in the Maximum Stay-Down Distance parameter. The Keep Tool Down parameter is responsible for keeping the tool down so that when moving to the next area to be machined, the tool does not retract to a safe height. If you set Safe Distance = 40 and Axial Stock to Leave = -5, movement between areas and the start of work with the work feedrate will be at 35 mm above the material.Īfter selecting the Keep Tool Down option, the Maximum Stay-Down Distance parameter is activated. Keep in mind that this also works the other way, as the allowance will be negative. At this height there will also be moving between machining areas. If the value Safe Distance = 40 and Axial Stock to Leave = 5, the tool will start working, with a federate, 45 mm above the material. Note, that the Safe Distance value takes into account the allowance left in the Stock to Leave section. You can see the difference in level from which the tool will start working with the work feed and level on which it will move to the next area. Now the tool path will look like in the figure below. It is also the height at which the tool will move between the machining areas. The Safe Distance parameter is responsible for the value of safe height from which the tool will start working with the specified feedrate.
The first two options in the Linking section are the same as for planning operation and have already been discussed previously. The last tab in the contour machining is the Linking tab.Īs we can see there are many more options here than in the case of Face operation.
