Anyhow, I’m doing a plaque for my daughter and got one of those nice looking amana tool 45° vee bits. I want to v carve in some tulipwood I have so just wandering the best speeds and feeds for this bit. 4mm deep the writing will be. For some reason when I enter the vee bits dimensions in carbide it defaults to a pass depth of 23.7mm so I have to manually adjust to 4mm
I’m not familiar with Tulipwood but a quick search indicates that it is in the poplar family. I wonder if it is a good candidate for V Carving as it is fairly soft and stringy. When you mention a 45deg V bit do you mean per side or total? The defaults in Carbide Create are not appropriate for the Shapeoko.
According to the Amana F&S chart for V bit, For the 45 deg, Amana recommends a feed rate of 40" a chip load per tooth of .0024" and a plunge of 20". Normally, the F&S from Amana can be at the upper end for the Shapeoko so maybe you want to use this as maximum.
Many call poplar “Tulipwood Popular”. If you are vcarving with a 45 degree bit you cannot set depth with carbide create. The depth is determined by the width of the line. The bit will try to touch both sides of a line and will cut as deep as it takes for both sides of the 1/2 inch bit to touch both sides at once. If the line is wider than the bit then the depth will go even deeper. . So if the line is 1/2 inch wide the cut will be around 1/2 inch deep. Some of the Vetric projects may set depth but not carbide create. This question of how deep a v carving will be is discussed in many posts to the forum. Please look up some of these before you start.
