Here's the step-by-step guide on how to use augmented-carpentry with a sword saw to realize basic joints: half-lap, and mainly butt joints. The feedback system is similar to the one for chainsaws.
Step-by-step¶
This is the overview of the feedback and widget system to assist you during the cut.
a - Feedback for blade rotation (in degrees). The goal is to diminish the line length corresponding to the angle error, to zero (green).
b - Feedback for balde position (in cm). The goal is to diminish the line length corresponding to the position error, to zero (green).
c,e - This is particular to the chainsaw feedback system. In order to obtain straight cuts both the base and tip of the chain needs to have equal heights. The yellow lines represent the distance to the bottom faces of bottom and tip blade. The idea is to have equidistant heights so that the two lines become green. The value d:00 represents the shortest distances of both.
d - The blade projection on the bottom face.
Adjust now the position until the indicator becomes green.
Adjust now the rotation until the indicator becomes green.
Now you can start cutting. During the cut make sure to keep the position and rotation values green, and push through the end of the cut. Stop before the value d:00 is 0. This means that the blade reached the opposite joint face. In this case we stop a bit before.
Now you can start cutting. During the cut make sure to keep the position and rotation values green, and push through the end of the cut. If good, you can mark it as Done just like the chainsaw.
Butt joints
a - position feedback
b - rotation feedback
c - blade's axis projection on the timber volume
d - blade's thickness projection on the timber volume
e - active cutting face
f - 3D model bounding box limits
g - timber piece bounding box limits
