technological advances after the Civil War.
Design for Manufacturing and
Assembly Final Semester Project
University of Cincinnati - Mech -6069
Introduction and Background:
This paper will critique the current design of the nut cracker.
processing and manufacturing operations will be anal
Assignment 4: Manufacturing Tolerancing
The cost of the nut crusher is made up three main components, the purchased material,
the component manufacturing and the assembly process. The assembly process and material
specification were addressed during the p
Assignment 3: Material Selection
During design phase, there are items of consideration which need to be well thought of as
pertained to material selection. First, FDA regulations and best practices for food safety need to
be well understood as these rules
Salvage: is the recovery of materials from existing sites for reuse on other sites.
1. Salvaged materials: are construction materials recovered from existing
buildings or sites and reused on-site.
2. Schematic design: is the concept and basic
NOTES: VEHICLES THROUGH WETLANDS
1. Vehicles that have reduced emissions and/or high fuel-efficiency: are
vehicles that are either classified as Zero Emission Vehicles (ZEV) by the
California Air Resources Board or that have achieved a minimum green score
NOTES: STAKES AND VEGETARIANS
1. Stakeholders: may include, but are not limited to, the following: neighbors
(e.g., residential, commercial, industrial, institutional-education, religious,
government, non-profit), interest groups (e.g., growth management,
1. Principles and goals: are defined as follows: principleguiding
overarching concept; goalobservable and measurable end result having one or
more objectives to be achieved within a more or less fixed time frame.
2. Program plan: is a narrative
1. On-going consumables: are materials that are regularly used and replaced
through the course of business. These materials can include, but are not limited
to, paper, glass, plastics, cardboard, and metals.
2. Open-grid pavement: is pavement
Graywater: is domestic wastewater composed of wash water from kitchen,
bathroom, and laundry sinks, tubs, and washers.
1. Greenfield: is a site that has not been previously developed or graded,
including previous agricultural fields.
1. Control of Invasives: is the appropriate eradication, suppression, reduction,
or management of invasive species populations, prevention of the spread of
invasive species from areas where they are present, and taking steps such as
1. Average buffer width: can be calculated using perpendicular transects
every 50 feet along a water body for at least 90 percent of the stream or
shoreline length within the boundaries of the site. For final average buffer
widths, a minimum b
Lowest-cost comparable item: is the most inexpensive item that provides a
desired function (such as light emittance) for the site. For example, the lowestcost light bulb that meets the sites lumen requirements (whether it be
