Development of a Clamping Fixture for Engraving

The diploma thesis presents the reasons for developing a new ** clamping** ** fixture** and its ** development. During the development of the clamping fixture, it was concluded that for a stable process, an excellently designed and ** constructed ** fixture** ** is** ** not** ** sufficient. ** Quality ** depends** on the ** responsibility** and ** precision** of the ** operator, the quality of the ** tool, the quality of the ** material, the ** method ** of** ** placing** workpieces for the next stage, and the responsibility towards workpieces of ** all** ** employees** who handle them at all stages of processing.

Solution and Method

The diploma thesis presents the reasons for developing a new ** clamping** ** fixture** and its ** development. ** Aluminium ** handles** for refrigerators will be manufactured. It turned out that the old clamping method no longer meets the set objectives.

Due to increased annual orders and excessive amounts of scrap or repairs due to imprints and damage during production, they were forced to change the clamping technology and workpiece manufacturing. When designing the clamping fixture, they decided to combine two operations, namely machining and ** engraving** on a ** CNC** ** machining** ** centre**. They opted for combining two operations due to poor engraving quality performed on the engraving machine, because the workpieces were greasy and the engraving was uneven, making it harder to achieve tolerances.

Another problem was the breakdown of the engraving machine, for which there was no alternative. With the new clamping fixture, they achieved a more stable, reliable, and precise process. They saved time dedicated to setting up the fixture on the machine, the cost of scrap and repairs decreased, and damage to workpieces was reduced.

Five pieces are machined simultaneously (previously three), which from an ergonomic perspective represents less strain for the worker. The diploma thesis describes the ** process** ** of** ** developing** the ** clamping** ** fixture, from the initial ** idea to ** cost** ** analysis, ** fixture ** design, ** manufacturing, to ** handover** to regular production when the documentation is completed.

Results

During the development of the clamping fixture, it was concluded that for a stable process, an excellently designed and constructed ** fixture** ** is** ** not** ** sufficient. ** Quality ** depends** on the ** responsibility** and ** precision** of the ** operator, the quality of the ** tool, the quality of the ** material, the ** method ** of** ** placing** workpieces for the next stage, and the responsibility towards workpieces of ** all** ** employees** who handle them at all stages of processing.
