112 TPM-A Route to World-Class Performance

4 Principles What is the true function of the adjustment operation as a
whole?
5 Causal factors What conditions create the need for adjustment?
6 Alternatives What improvements will eliminate the need for adjustment?
Figure 5.32 provides a clear visual presentation of the TPM approach to
analysing adjustment operations leading to minimization of losses. Figure
5.33 reviews progressively the process from an analysis of the present position
right through to achieving optimal conditions. Wherever possible, make use
of video: it is a very powerful analysis tool.

W Progress in reducing set-up times
W Variable factors
Analyse set-up data Problems
W Points requiring attention
I W Equipment mechanisdsystem

W Effectiveness of each operation

Set improvement targets W Targets based on equipment restrictions
(the challenge) W Targets based on desired improvement

W Tools

W Practise thoroughly
Establish work sequences
for internal set-up Co-ordinate work sequences and methods
