Week 2:- BiW Fixture Basics Challenge
Que 1-What is the process of project excecution activity
In Project excecution activity basically it involves the complete activity of project or product has to be done .
For example if we have to make the fixture for fulfil the requirement of the customer for that customer has given the requirement
called as RFQ , for that we have to study the all technical specification , need to calculate the complete time to make it final according to that we have to submit our technical offer to them
Once we received the PO then we have to start the working on it ,Need to define the timeline to complete the activity .
we need to take the trial at customer end & have to prove out the fixture that has to be work properly .
Check the attached project process flow .
Que 2- What are the Types of joining process?
There are two types of joining processes that are
1- Mechanical Joining
2- Metallurgical Joining
Que 3- What is the resistance welding & its applications in automotive sector
1- Resistance welding - Resistance welding is widely used in manufacturing industry to join the metal & sheet components.
In resistance welding there are three types
1-Resistance spot welding
2- Resistance seam welding
3-Resistance projection welding
Applications of resistance welding in automotive sector
1- Resistace welding mostly used to manufacture the radiators
2- To manufacturing of containers
3-To weld the Heat exchangers.
Que 4- What is the 3-2-1 principle?
To better understanding of 3-2-1 principle we are considering the 6 degrees of freedom 3 are the translations & 3 are the rotational .
In 3 degrees of freedom we are restricting the 1 translation moment and two are the rotational moment
In 2 degrees of freedom we are restricting the 2 translation moments in X & Y directions
and at last we are considering the 1 rotational motion .
basically we have to hold the part / arrest the part in such a way that part can constrain / lock for 12 degrees of freedom .
Que 5- Define Body coordinates system
Ans- A coordinate system is reference system consisting of set of lines , points and surfaces , used to define the positions of the points in space in either two or three dimensions .
in general Body coordinate system is also called the car line or body line
Que 6 - Elaborate body plane system & its essentials .
Ans- Body planes are the reference planes in automotive car . Thease planes are used to define the GD & T of all car parts in a automotive domain .
Body planes are three mutually perpendicular imaginary planes .Thease are usually considered to be present at the driver position or sometimes at the engine position .
Bodyline dimensions are essential for the below reasons .
1-Fixed origin
2- Flawless design for assymbly
3-Assist the easy locations of different parts in a vehicle
4- Helps to create the standardize system
5 - It would also help for checking the quality .
