t-slot undercut 3axis milling

[Markus Roth]

Hello Forum,

 

with search, i found some topics, which helped me to get almost done, what i want. If possible, have a look at tslot-undercut.mc9 on the ftp. It looks pretty nice, but has on the "upper half" of the path some strange retracts, i cant explain myself. Anybody can figure it out?

 

Also, is it possible to rough this part with the t-slot mill? I tried rough/contour and rough/flowline, but had just no luck, when i applied the settings under gaps/check collision like in my programmed finishing flowline..

 

best regards,

 

Markus

in the same folder have a look on TSLOT-UNDERCUTWTP.ZIP .

I made one rough operation with surface-contour

You can use surface -pocket too with similar approach .

Change settings to your taste ,add needed ammount of offsets to approach according to tool and material ,change settings for tolerance and stepping for finish

enjoy

 

Winnie teh I can make surface pocket operation too ,but I am busy now ,may be later

Helle Winnieh,

 

that looks excellent! really! :-)but, if i understand your answer right, then rough/pocket is the only way to rough it? no flowline or contour roughing out this profile from the full material? i had something in mind like the 2dswept and then use the swept2r chook. but there, i have the problem with the gouge of upper half..

Or rough pocket ,or a couple of surface contours with different stock to leave ,or draw simple section ,make contours based on it ,use common contour toolpath to rough materrial and then surface -contour

Be a bit creatibe .

Or look deaper in your flowline parameters and geometry

 

I can make rough toolpath later ,maybe
