Haimer bundles all these components together via new software that enables the consistent exchange of tool data, linking it to a digital Industry 4.0 system.
DAC (Data Analyzer and Controller) is the name of the tool management system developed by Haimer which has been used for some time in its own manufacturing facility in Igenhausen, Germany and will be available for purchase after EMO 2019.
It manages the exchange of target and actual values as well as other tool data between the individual toolroom stations and establishes the connection to the corporate network. In combination with RFID data chips – optionally available on Haimer toolholders – or via QR or Data Matrix codes (which can be read out and evaluated by different systems via a scanner), the Haimer DAC allows a clear identification of the complete tool.
Through the network connection, it also provides additional tool data: assembly instructions, article numbers, stock adjustment, and 3D models. In addition, DAC supports the user in the analysis of production data and process optimisation.
This is how the Haimer DAC tool management works: in the CAD/CAM system, a tool order is generated and sent to the DAC. There, a tool identifier ID is assigned, which accompanies the tool from then on.
These are followed by stations assembly (e.g. shrinking), measuring and balancing, all of which communicate with the DAC. After the last value transfer, data is sent to the machine tool control and the magazine location is specified there.
Depending on the balancing quality, an adaptation (for example, reduction) of the maximum speed on the machine takes place. After processing, a retransmission of the remaining tool life to the DAC takes place. Magazine location errors can be eliminated by scanning the tool ID number on the machine. The user controls the entire process by clicking and confirming or accepting values.
Since no manual input is required or possible, there are no false inputs or collision risks. Managing director Andreas Haimer explains: "With the DAC, we want to make digitalisation in tool management feasible for small and medium-sized companies as well as larger businesses. The concept is scalable from small to large, and it can flexibly be connected to existing presetting devices as well as various CAD/CAM or control systems.
Another highlight on the Haimer stand is a robot cell demonstrating automated tool presetting, comprising a tool trolley equipped with toolholders and tools. On a presetting device Microset VIO linear toolshrink, the tools are custom shrunk and preset and after cooling, the balancing quality of the respective complete tool is checked.
The completely assembled and tested tool is then stored on a second tool trolley and is thus released for use. All handling is carried out via a robot. Andreas Haimer points out: “Automation is beneficial only if the implemented hardware is 100% reliable. All of our products are so robust and designed for durability that they ensure maximum process reliability and are suitable for all types of automation."
Haimer also focuses on tool (clamping) solutions for turning. With Haimer Duo-Lock and shrink fit collets for driven tools, tool changes can be completed accurately and reliably on the machine which results in reduced set-up times and higher productivity.
The shrink fit collet range has been extended to include sizes ER 11 and ER 32. In order to optimise the tool change for shrink fit collets, a newly designed shrinking device will be presented in Hannover, which handles the heating and cooling of the collets in different lengths easily.
There are also new toolholders for cutting tools: for example, Haimer will be offering BT30 and BT40 toolholders with a face contact that will contribute to even greater precision and process reliability, especially at high speeds.
In October, these toolholders will be available from stock as shrink fit chucks in Standard Shrink Chuck, Power Mini Shrink Chuck and Power Chuck versions.
