Hello all,
Extreme novice machinist in training here. I’m currently enrolled in a CNC course at the local community college. We’ve covered a number of basic skills so far such as setting work coordinates, tool length offsets, dialing in a vise, picking up an edge, picking up holes and bosses, etc. We’ve also got the chance to run a few programs to make some parts out of stock that we squared up on the manual mills during the last course that I took.
This last week, homework has been about using trigonometric functions and right triangles to find missing dimensions on prints. It’s been very challenging for me as before these classes I haven’t really done math since about 2005 in college. haha. And even then I never did take a trig class. So I’ve kind of given myself a YouTube crash course in trigonometry over the last week and learned Pythagorean Theorem and all that so I could maybe understand what we’re currently learning.
I’ll attach a pic to this post. What they’re looking for is for us to be able to calculate the two XY points of a blend arc. I’m not asking for anyone to do my homework but I feel if I could at least see the right triangles required to do the math I might have an ah ha moment and be able to figure out other similar problems with missing dimensions. So if anyone would care to draw the required triangles or point me in the direction of a good resource it would be much appreciated. I’m just trying to learn all I can and this stuff has me stumped. I have class again on Thursday and would like to come in with some knowledge.
Thanks for any help. Hopefully this was the correct forum to post in.
