Test items:

• Testing the dimensions of the inner diameter in the vertical and horizontal directions
• Testing the outer diameter size
• Height measurement test
• Testing the width and length dimensions
• Testing the height of the first floor

The test piece consists of a cube base with an edge length of 10mm, on which a hollow tube with a diameter of 10mm is fitted. It undergoes multi-dimensional changes in the following parameters:

• Outer diameter range: from 9.6mm to 10.4mm, with a center position of 10mm. The width, length, and outer diameter can be flexibly adjusted in increments of 0.1mm.
• Internal diameter range: from 5.6mm to 6.4mm, with the center position being 6mm. The adjustment is made in increments of 0.1mm, allowing for precise control of the internal diameter size.
• Height range: from 9.2mm to 10.8mm, with the center position at 10mm, and a step size of 0.2mm, allowing flexible adjustment of the cube's height.
• Tube height range: from 4.2mm to 5.5mm, with a center position of 5mm. Each increment is 0.2mm, allowing for precise control of the tube height.
