how to calculate material removal volume
i need to find out the material removal volume for turning parts during processing.
basicly, this can be done by building a stock outside (cylinder) and substracting the part volume from the stock volume. the part's volume can be calculated using mass properties.
do you know
1.how to build a stock which can include the parts and
2.calculate the removal volume using api and vc++?
thank you!
have a library of all stock parts as a whole, and then for each part create a little tool that gets the active parts mass, and asks you to select a stock item to make it from, then open that model, get its mass and subtract the parts mass. job done
