1. Workpiece: Engine block.

2. Task: In the first operation, machine the surface of the engine housing marked in red.

3. Process: Design tooling on the mounting plate.

The flatness requirement for the underside of the mounting plate is 0.01, and the positioning holes for the connecting pull studs must be maintained within a tolerance of 200 mm ±0.01 mm. (The ±0.01 mm tolerance is a recommended value; should the deviation exceed this range, the Zero Clamp system will compensate for the error, bringing it within a range of ±0.1 mm.)

Fixture 1 is secured to the Zero-Clamp zero-point system via positioning pull studs, enabling the first machining operation to be performed.

As above, design fixture 2 on the mounting plate to complete the second operation.
