1. Development of Cone Drawing steps explained B y : SUB IN B M A R K O S E A s sistan t Profe s s or DEPARTMENT OF MECHANICAL ENGINEERING, ASET 1

2. Question Draw the development of a cone of 50 mm diameter having height 60 mm. DEPARTMENT OF MECHANICAL ENGINEERING, ASET 2

3. Step 1 Draw the front and top view of the cone. DEPARTMENT OF MECHANICAL ENGINEERING, ASET 3

4. DEPARTMENT OF MECHANICAL ENGINEERING, ASET 4

5. Step 2 Divide the top view into 8 equal segments. Name the points as shown. DEPARTMENT OF MECHANICAL ENGINEERING, ASET 5

6. DEPARTMENT OF MECHANICAL ENGINEERING, ASET 6

7. Step 3 Draw a line segment of length = O’ – 1’ with reference to front view. DEPARTMENT OF MECHANICAL ENGINEERING, ASET 7

8. DEPARTMENT OF MECHANICAL ENGINEERING, ASET 8

9. Step 4 Draw an arc with radius = O – 1 i.e. length of line segment. DEPARTMENT OF MECHANICAL ENGINEERING, ASET 9

10. DEPARTMENT OF MECHANICAL ENGINEERING, ASET 10

11. Step 5 Now the arc is being segmented. On the compass measure the distance of arc on the top view (1-2). Cut the main arc with radius = 1-2 DEPARTMENT OF MECHANICAL ENGINEERING, ASET 11
