- Review product manual. All product manuals can be found at: https://www.motoman.com/en-us/service-training/product-documentation
- Consult Yaskawa Engineering or Motosize (Authorized Integrator Access only) for positioner loading calculations.
- If your positioner has modification--such as a custom MotoMount--refer to the technical details of those modifications to make necessary adjustments to tooling design.
- Maintain the net weight of the tooling, parts, and utilities under the weight capacity of the positioner.
- For fixture length, build fixtures to +/- 1mm of the pin-to-pin distance. The actual total tool length can longer than the pin-to-pin distance up to the MotoMount block thickness.
- Fixture width needs to be such that the fixture is contained in the turning envelope
- Maintain the Center of Gravity (CG) of the loaded tooling within the equipment specifications. The CG can be moved in tooling by adding ballast at the correct location if the positioner weight limit is not exceeded.
- If using an MH (Headstock only) maintain the load overhang within positioner specifications.
- Consult the CG Offset and overhang diagrams in the product bulletins.
- For an MHT (Headstock with tailstock), tooling should align on the MotoMount block location pin and bolt on to all 4 bolt holes. Do not use spacers between the tooling flange and the MotoMount, as it could result in having unsupported lengths of screws which can behave as thin columns and flex.
- When designing tooling ensure that there is enough stiffness and rigidity to resist torsion and bending.
- For an MHT: If the tool is not stiff enough for bending it will sag causing the MotoMount to tilt. If the MotoMount tilts beyond its physical limit it will lock up causing inconsistent positioning and will damage the MotoMount. If the tool does not have enough torsional stiffness, then the slave side of the fixture will lag the driven side of the fixture creating additional stresses and potentially damaging the tooling.
-
When mounting tooling of dissimilar metals, ensure proper material compatibility and preparation. This includes selecting appropriate fastening methods, adhesives, or welding techniques to mitigate risks such as galvanic corrosion, differential thermal expansion, and mechanical stress.
- WARNING: Failure to comply with any of these items may result in equipment damage, facility damage, potential safety issues, increased positioner stopping times, and voiding of positioner warranty.
