The milling machine in a manufacturing facility solution is written in python and is given below.

<h3>
The code that determines the minimum number of forward and backward moves is given as?</h3>

def toolchanger(tools, k, desiredTool):

# either we move forward or backwards in the array

# we also have to find which tool isballendmill closer

# is there a way we can re-arrange the array to

i = k

while True:

if tools[i % len(tools)] == desiredTool:

print(tools[i % len(tools)])

print("no of steps : ", i)

return True

i=i+1

if __name__ == "__main__":

tools = ["ballendmill", "hammer", "keywaycutter", "slotdrill", "facemill", "nail", "drill"]

k = 2

target = "ballendmill"

minNumSteps = toolchanger(tools, k, target)

print(minNumSteps)

Full Question:

"A milling machine in a manufacturing facility has a tool change system. The took changer holds tools and some duplicate 5 tools may be included. The operation mus. move through the tools one at a time, 13 14 either moving forward or backward. The tool changer is arranged circularly, so IS 15 11 when you reach the last tool in the tool changer, pressing next takes to you to beginning and vice versa. 21 Given the index of the desired tool in the tools, determine the minimum number of forward or backward moves needed to reach a certain tool."

DENIUS [597]

The Angle HCA is equal to 52°. This is arrived at using the knowledge of the Total value of Angles in a Triangle and the Total Value of Angles in a Polygon.

<h3>What other principles were used to arrive at the answer?</h3>

The other principles of mathematics that were used to arrive at the above answer are:

Total Angles on a straight line;
Total Angles on a point; and
Line segments.

<h3>What are the Steps to the Solution? </h3>

Step 1 - Recall that we have been given Angles AHB and BAH to be 128° and 28° respectively.

We also know that:

The sum of angles in a triangle is 180°;...................A
The sum of angles on a straight line is 180°;.........B
The sum of angles in a polygon is 360°; while.....C
The total sum of angles at a point is 360°.............D

Since A...therefore:

When ∠AHB (128°) and ∠BAH are taken from 180° we have DBA = ∠28°.

By observation, we can deduce that ∠BDE, ∠CDH, ∠CEH and ∠AEH are all right-angled triangles.

Using the above, we are able to repeat this process of solving for each angle until we have ∠HCA.

To verify that our answer is correct, recall that sum of angles in a polygon is 360°

That means:

∠BDA + ∠DHE + ∠CEH + ∠HCA = 360°

That is, 90+ 128 + 90 + 52 = 360°
