SUCCESSFUL AUTOMATION AND WORKHOLDING INSTALLATION: Royal Workholding

Automation is taking a key role on the manufacturing floor to improve quality, production, and to stay competitive in obtaining contracts.

 Automation, whether a Robot, Gantry, or Pick and Place Load device, provides consistency in the Load/Unload Operation. It can operate continuously, thus reducing downtime and allowing management to concentrate on key areas of production.

Many people have felt threatened by automation in the sense that it would be replacing them. However, this has proven wrong. Automation has kept us competitive with other countries that have much lower labor costs. Plus, it has also created new and safer career jobs…making manufacturing a much more appealing career.

However, in many instances companies take the wrong approach and jump into
the automation trend with little thought of all the aspects of integration with the machine, tooling and fixturing. To avoid this mistaken approach It is always wise to consider visiting companies that have taken the path to automation and learn what obstacles they have had or mistakes they have made…and then learn from their solutions.

Automation requires open communication between the Machine Tool, Fixture and Robot providers.

Many prefer to go to the Machine Builder or Dealer who have the personnel to provide a turnkey proposal. Since communication must pass through the machine control, it is recommended that machine personnel lead the project and do the integration.

 

In addition, through the Machine Control the workholding device has to communicate with the machine as well as the automation regarding such
actions as:

  • Clamp/ Unclamp confirmation.
  • Clamp Pressure monitor.
  • Part seat confirmation.
  • Spindle On/ Off.

These specific actions allow or disallow certain actions of the machine and automation.

Be certain to consider all the possibilities and requirements prior to installation.

By not doing a thorough sequence of events…including all the options and possibilities… could possibly lead to a poor and disastrous installation.

Certain actions are a must, such as:

  • Stopping the spindle before unclamping the part.
  • Unclamping the part before the automation loads/unloads the part.
  • Cleaning of any chips from the fixture clamping and locating surface.
  • Preventing human intervention of the area while in operation.
