12.1.26. Ramping

Ramping can be used to lower the strain on the tool when plunging into the material. When ramping is activated, the tool will go down at an angle and not straight down in Z as it normally does.
 
Consider the following part:
 
 
As you can see from the red toolpath line, we are going straight down in Z to contour depth. Let's use ramping instead to make a toolpath with less strain on the tool.
 
Open the parameters for the contour cut layer and click on the Ramping tab.
 
 
You can either accept the calculated default values or enter your own.
 
 
Now the tool moves down in a sick-sack pattern.
 
It is up to you to calculate the optimal Ramping Angle and length.
 
Please note that ramping cannot be done on arcs. Also, if your Ramp Length (L) value is longer than the first linear movement, the ramp will continue on the next linear movement and so on. Therefore, you need linear movements with a summed length longer than the Ramp Length to avoid an error.
 
 
Ramping with a length overlapping the first three linear movements in the contour.
 
Ramping and Stepping can be combined. See Stepping.
