Door Arm Rest Week 8 Challenge

CREATION OF TOOLING AXIS , CLASS B AND C CREATION AND CREATION OF SOLID AND DRAFT ANALYSIS OF THE DOOR ARM REST

TOOLING AXIS

Y AXIS

• first the base is extracted and mid point is created
• then a axis system is created using the point and create a dummy tool axis along z
• then intersection of the class a with the axis along y axis
• here there are two parallel faces and two lines are drawn respectively and they are bisected to create a tooling along y

X AXIS

• the x axis first a plane is created and sketch is created in the plane
• angle is assigned to the sketch line and draft analysis is done simultaneously and the angle is adjusted untill arrived at disired draft
• the x axis tool axis is made the main tool axis

SIDE CORE

• because of the parallel faces to the main tooling axis side core is required and is created using the midpoint and along y axis

DRAFT ANALYSIS OF CLASS A

• the class a is draft analysed using the main tooling axis and it was not clearing on some areas and it is needed to rework on the class a

CLASS B

BASE

• first the base is extracted and is untrimmed and is offseted to 2.5mm

SIDE WALL

• then the side walls of the inner cavity is extracted and untimmed
• then they are extrapolated
• then offseted to 2.5mm
• finally they are trimmed with the base

OUTER HALF

• first the outer top face and the side face are extracted and is untrimmed
• then they are extrapolated and trimmed
• their outer boundries are also extrapolated using the boundry and smooth curve

INNER HALF

• it has two faces upper and side
• first the upper side is extracted and the edges are created using the multiple extracting the boundries and made into smooth curves and are extrapolarted and are joined and offseted
• in similar way the side face is also extrapolated and offseted
• finally both the extrapolated faces are trimmed
• finally trim is then filleted

CONNECTING SURFACE

• here the connecting is first extracted using the filleted line using point and a line through the point and then fillet line is extracted and is sweeped and offseted
• then another small patch on the top side is extracted and and split using the lines to get proper surface and is offseted
• then the blend option is used to create blend connecting the top and side face

FINAL TRIMS

• then the outer and inner surface are trimmed with the connecting surface
• then the trim is again trimmed with the sidewall trim
• then the required fillet are given to get the required class b

CLASS C

• the faces wich lie perpendicular to the tooling axis are created using the sweep with draft and minimum of 3 deg draft is given
• the other faces which are parallel to the tooling axis are sweep with respect to the surfaces
• then other faces are connected using multi section surface
• and sharp corneres are extrapolated and are trimmed
• finall c is joined and also extended little above as a is not intersecting at the sharp corners
• finally the class c and class a are trimmed together

SOLID TRIM

• then finally the trimmed class c and the class b is finally trimmed to create closed surface
• then the creatred surface is converted into solid by using the closed body option

FINAL DRAFT

• then the final draft is created for the solid using the main tool axis
• then green colour signifies the faces getting cleared in the tooling axis
• there are certain red and blue zone in the c surface which indicate rework on the class a surface
