I'm trying to cut a 1/4" slot with a 1/4" bit in Partworks and the tool path ware says the bit will not fit the vector at machining depth. The vector is a rectangle 1/4" wide and some greater length with 1/8" radiused corners. It seems to me it should fit. Any ideas? I could use a smaler bit but all the other cuts on this project use the 1/4" bit so I don't want to change. Bit is a 1/4" spiral upcut.
