Fast setup cuts coupling inventory

A Huco Dynatork product story
Edited by the Engineeringtalk editorial team Jun 4, 2008

Huco Dynatork has invested in quick-setup machine tools that will form a dedicated production cell for Oldham couplings, slashing lead times.

Value stream mapping has identified an appropriate development path that will see Oldham lead times plunge from weeks to days.

An early aim of the mapping exercise was to identify time or material waste and excessive inventory and it soon became clear that a major contributor to lead time was product queuing at every stage of manufacture.

Initial analysis set a typical lead time for a nonstocked item at an unacceptable 27 working days.

Huco Dynatork had already taken some steps to iron out the production queuing by holding a large stock of pilot bored Oldhams.

The problem was that market demand required a huge inventory and that was certainly not producing a good return on capital.

"An inventory-based system can only be as good as your forecast", explained Joint Managing Director David Lockett.

"The scope of choice we offer our customers means we will never be able to forecast accurately every item so we have focused our attention on creating greater production flexibility".

Huco Dynatork has therefore invested in quick-setup machine tools that will form a dedicated production cell for Oldham couplings.

In the coming months this will comprise four CNC turning centres and two CNC vertical milling centres.

Before committing to the purchase of this capital equipment the company undertook future state value stream mapping, an exercise that assumed the mix and manufacturing volume of the product remain unchanged.

The plan showed a massive reduction in inventory and the typical lead time for a nonstocked Oldham was reduced to five days.
