QUESTION 2: LOCI (CAM)

Given:

© The detail of a camshaft and a wedge-shaped
follower at the minimum distance from the camshaft
centre

* The position of centre point P on the drawing sheet

Specifications:

» The wedge-shaped foltower reciprocates along a
60° line that passes through the centre of the
camshaft.

¢ The minimum distance from the follower to the
centre of the camshaft = 20 mm

* Rotation = anti-clockwise

Motion:

The cam imparts the following motion to the wedge-

shaped follower:

elt rises 40 mm over the first 60° with Uniform motion.

* There is a dwell period for the next 30°.

* It rises to its maximum displacement of 80 mm over
the next 90° with uniform motion.

It descends 40 mm over the next 90° with simple
harmonic motion.

eltretums original position with uniform
acceleration and retardation over the remainder of
the rotation.

Instructions:

Using centre point P on the drawing sheet, draw, to
scale 1: 1, the camshaft and wedge-shaped
follower in the given position.

¢ Draw to a rotational scale of 30° = 8 mm and a
displacement scale of 1: 1, the complete
displacement graph for the required motion,

Using the given position of the follower as 0°, project
and draw the cam profile from the displacement
graph.

* Indicate the direction of rotation on the cam profile
with an arrow.

* Indicate the rotational scale of the graph.

¢ Show ALL construction and projection. 137]

QUESTION 4: MECHANICAL ASSEMBLY

Given:

* Orthographic views of each part of the fixed lathe steady
assembly,

* The exploded isometric drawing of the parts of a fixed
lathe steady assembly, showing the position of each part
relative to all the others

Instructions:
© Answer this question on page 6.
© Draw, to scale 1 : 1 and in third-angle orthographic
projection, the following views of the assembled parts of
the fixed lathe steady assembly:
4.1. The front view as seen from the direction of the
arrow on the exploded isometric drawing.
4.2 Asectional left view on cutting plane A-A. The
cutting plane is shown on the front view of the
base {part 1).

NOTE:

« Planning is essential.

The convention of symmetry may NOT be applied.

The drawing must comply with the SANS 101117
guidelines.

© Draw the guide (part 6), adjusting screw (part 7), screw
cap (part 8) and the ring (part 9) only in the top hole
marked B.

« Draw only the top lock screw (part 4) in position, as shown
in the exploded isometric drawing.

* Show THREE faces of the M10 bolt (part 5) in the front
view.
