Week 9 - Project 1 - Door Applique Design with Engineering Features

AIM:

TO Create the Base Bracket Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model. Create the Heat Stakes and the locators considering the design rules mentioned in the video for the door applique.

PROCEDURE:

*Join all the component into one component and name it as CLASS A SURFACE.

*Create a tooling axis in the Y direction.

*Now,draft anlysis the class A with the tooling axis.

*now,create a geometrical set and name it as class b surface and offset the class a for 2.5mm and extrapolate them.

*create a geometrical set as class c surface and crrate a boundary and set in point countinuity and give the smooth curve and again offset the class a and extrapolate them,finally trim them together .now the claa c surface is formed.

*now,join the class a and class c together and trim the class b and join.now we get the thickness.

HEAT STAKING:

Heat staking also known as thermoplastic staking is the process of joining two dissimilar materials together. In heat staking we use local heating and cooling to raise the temperature of plastic components and allow plastic reforming to be carried out. This reforming can be used in a wide variety of applications.

The 3-2-1 principle of location (six point location principle) is used to constrain the movement of workpiece along the three axes XX, YY, and ZZ. This is achieved by providing six locating points, 3 pins in base plate, 2 pins in vertical plane and 1 pin in a plane which is perpendicular to first two planes.

The degree of freedom defines as the capability of a body to move. Consider a rectangular box, in space the box is capable of moving in twelve different directions (six rotational and six axial). Each direction of movement is counted as one degree of freedom. i.e. a body in space has twelve degree of freedom.

Create a geometrical set as locaters and cffeate a point and the plane for the sketck to create a locaters .now,we are going to create a 4 way locater for that create a sketch and draw the line now pasd the locater and chamfer the locater for 0.5mm and give the fillet value.

to create a another four way locater copy the pervious 4 locater and give past special and result with link now translate the locater with the coordinates.now,another 4 way locater was created.

now,create a new positioned sketch for the tow way locater and pad the locater and chamfer and give the fillet value to the locater.now two way locater was created.

now,assemble the three above mentioned bod in single body.and now the 4&2 way locater has been created.

now,we want to create a heat steakes for that do extract and multiple extract the suraces and give the boundary on the surface and offseet them and give the points in plane and points reference.

create one sketch and pad the sketch and give chamfer value as 0.5 .

now,we dont want to create a for that we can use the paste special option and and create a heat steak with the points.

now, we have created the heat steak successfully,

now,we have to create a hole in the door attachment.create a sketch and pad it and revome this body with the door attachement the hole will be created.

create another sketch to create a hole for heat steak and pad them.we don't want to create sketches for all the steak for that we can give the paste special and translate them.now give the remove with the door attachement,the hole will be created for door attachement.

the gap between hole and the locaters should be .1 or lesser then that.

CONCLUSION:

Successfully,we have created a locater and heat steak in the door applique.
