Instructions:

Task $2$ is to write a program for the turning lathe to produce a chess piece $-$ Rook as shown below.

The program when finished is to be entered into the machines allocated and stored under your name.

Each program will need to be verified first and then the work will be clamped into position.

You have the detailed dimensions attached to design the Rook based on the stock material provided.

Code should be written manually and typed as Text Document $($YOU CAN USE SOLIDWORKS

CAD PACKAGE TO DESIGN THE ROOK IN THIS TASK, BUT CODE SHOULD NOT

GENERATED BY SOLIDCAM$).$

Use the following assumption:

The stock material is of $62$ mm height and $31$ mm diameter at average.

Stock material should be facing $($minimised the height$)$ with $1$ mm as first pass and $(1-0.P)$ mm as

second pass $($ P $=79).$

You need to keep about $17$ mm considering we mount the rod in the chuck.

Try to fully make use of the material.

Appropriate tools $($with limitation of $2$ mm cut per pass of diameter as Rough cut and $1$ mm cut

per pass of diameter as finishing cut$)$ will be provided for turning operations. Assessment process:

Program to be assessed & verified before

machining.

Machining and machined block to be assessed

for efficient operation & finish, respectively.
