CHOOSING THE RIGHT TECHNICAL DESIGN
THE PURPOSE OF THE STUDY
Students are able to:1. Choose the right technical design
HOW TO CHOOSE THE RIGHT TECHNICAL DESIGN
1. Choose the working pieces
2. Choose the type of the projection
3. Give the measurement
4. Choose or state the cutting style
CHOSING THE WORKING PIECES
1. The shape: cylinder, square, triangle, etc.
2. The type: axis or hollow
CHOOSE THE TYPE OF THE PROJECTION
projection: a. Pictorial projection b. Orthogonal projection
PICTORIAL PROJECTION
1. Dimetric projection2. Isometric projection3. Resemble projection4. Perspective
ORTHOGONAL PROJECTION
1. European projection2. American projection
EUROPEAN PROJECTION
1. straight vision2. side vision3. upward vision
AMERICAN PROJECTION
1. upward vision2. straight vision3. side vision
STATE/ CHOOSE THE VISION
STRAIGHT VISION
Design that has many information
THE TOTAL VISION
1. suitable with the needs2. without any doubts
DESIGN POSITION
As the same as the position when it built
PARTLY VISION
It is used if the vision doesn’t give complete information
SPOT VISION
Replacing the simetric vision to make sure the design
SHORTENED- VISION
Searching on the suitable paper size
Repeated-vision
One circle, others are the fuses
STATE THE MEASUREMENT
1. The arrow
2. lines
3. measurement number
4. the symbol of the shape
THE ARROW
1. blocking2. measurement limit3. 1:3 comparing
THE LINE
1. continuing soft line2. inline with the
object line3. limited by 2 arrows
MEASUREMENT NUMBER
1. the number is on the horizontal line
2. the number is in the left side of the vertical line, down side
3. the unit should be the same, if it is not, it should be shown
MEASUREMENT SYMBOLS
ǿ diameter
without ǿ
MEASUREMENT SYMBOLS
sisi bujur segiempat sama 15 mm
square sides are 15 mm
R jari-jari (radius)
RADIUS SYMBOL
Symbol R
MEASUREMENT SYMBOL
Sǿ or SR for a ball
HOW TO STATE THE MEASUREMENT
By using coordinate
HOW TO STATE MEASUREMENT
The measurement is in one line
HOW TO STATE MEASUREMENT
The measurement on the design structure
CHOOSE THE CUTTING TYPE
To avoid the doubtscut the piece.
THE CUTTING DESIGN PLACEMENT
American projectionthe surface is placed behind the
arrow symbol
THE CUTTING DESIGN PLACEMENT
European projection:The surface is in front of the arrow symbol
STATE THE CUTTING DESIGN
Turned-cutting surface
THE TYPE OF CUTTING DESIGN
A. fully cutting
THE TYPE OF CUTTING DESIGN
a Half cutting
THE TYPE OF CUTTING DESIGN
C. Partly cutting
THE TYPE OF CUTTING DESIGN
D. Running cutting
THE TYPE OF CUTTING DESIGN
E. Turning-cutting
THE RIGHT DESIGN SAMPLE
FORMATIVE TEST
1. Mention the procedure to choose the right technical design!
2. Mention 2 examples to state the object vision! 3. Mention 4 steps to state the measurement on the
object!4. What is the reason making the cutting design?
