Expression for different stepdown depending on tool type

[sean.gorman]

Hi, 

I am looking for a way to create an expression to drive the stepover of a toolpath depending on the tool type (i.e. using contour with a ball mill as opposed to a square end mill). This is for using toolpaths such as contour with different tool types. 

for example: 

if tool_type - ball mill, stepover = 0.1

else tool_diameter*0.25

Any help would be appreciated. 

Thanks,

Hi @sean.gorman .

When I looked for it, the IF statement of expression looks like this.

<Evaluation expression> ? <Return_true> : <Return_false>

In this case.

tool_type == 'ball end mill' ? 0.1 : tool_diameter*0.25

I attached the file, please change the tool and try.
