Cost accounting is defined by the Institute of Management Accountants as "a systematic set of procedures for recording and ... tooling, production control, purchasing ...
Punching, and press work in general, is a process well suited to mass production. However the initial tooling costs, of both the machine and the job-specific press tool, are high. This limits punch work from being used for much small-volume and prototype work. A turret punch is one way of addressing this cost.
The simplicity of the rubber press tool causes tooling costs to be around 85 to 90% lower than those of regular deep drawing while the variable costs are higher. This combination makes rubber pad pressing very suitable for smaller and medium-sized series (up to 5,000-10,000 pieces per year), even though traditional cutting, lace, welding ...
The cost is determined by the number of features, which determine what tooling will need to be used. Engineers keep the features as simple as possible to keep the cost of tooling to a minimum. Features that are close together produce a problem because it may not provide enough clearance for the punch, which could result in another station.
Tooling may refer to: Machine tools and the tooling, such as cutting tools, fixtures, and accessories, that is used on them Cutting tool (machining), any of hundreds of kinds of cutters; Fixture (tool), a fixed workholding or support device; Jig (tool), a movable workholding or support device
Hydroformed bellows generally have a high tooling cost, but, when mass-produced, may have a lower piece price. However, hydroformed bellows have lower performance characteristics due to relatively thick walls and high stiffness. Welded metal bellows are produced with a lower initial tooling cost and maintain higher performance characteristics.
Spin casting is a favored method for fabricating items in the specified materials – low temperature metals and thermoset plastics. Compared to the two main competing processes, injection molding and (zinc) die-casting, spin casting has significant advantages in terms of startup cost and ease of use.
This affects the cost of tooling as well as the rate of production. [16] Thicker sections generally need an increased section size. In order for the material to flow properly legs should not be more than ten times longer than their thickness. If the cross-section is asymmetrical, adjacent sections should be as close to the same size as possible.
