Heat Treatment Process Routings
Heat Treatment is a secondary process group--these processes are applied in conjunction or subsequent to the primary manufacturing processes that are used to manufacture a part. As such, they are not available for selection when indicating the primary process group (for example, in the Production Info window or in the Select Primary Process Group window). Instead, you can Edit the process routing to include one or more Heat Treatment processes. All Heat Treatment processes are optional and by default they are not assigned automatically by aPriori, so you must include the processes of interest.
To include a Heat Treatment process in a routing (except for Plastic Molding routings)
1 In the Manufacturing Process pane, click the Edit menu and choose Routing Selection…
2 The Routing Selection window will appear. The second-to-last node of each routing is a Heat Treatment node (the last node is a Surface Treatment node). For the routing level of interest, click the + symbol to expand the Heat Treatment node into five nodes. The first node is an intermediate node called Heat Treat Processes and the next four nodes correspond to different types of follow-on processes (Straighten, Certification). Click the + symbol on the Heat Treat Processes node to expand it to nodes represent different categories of heat treatment processes (Surface/Case Hardening, Through Hardening, Annealing, Tempering, Solution Hardening, Aging/Precipitation Hardening, Stress Relief, and Cryogenic Freezing).
3 Click the + symbols on any of these category nodes to expand to the specific process(es) of interest. For example, expand the Surface Hardening node to show the Carburizing, Carbonitriding, and Induction Hardening processes.
4 To include a specific heat treatment or follow-on process in a routing, right-click on the process node and select Include from the popup menu. You can include multiple heat treatment and follow-on processes as appropriate (for example, you may wish to select Carburizing, Straightening, and Certification for a given part).
Note You must include the actual (lowest-level) process node. If you include only an intermediate node (such as Surface Hardening), aPriori does not automatically include the processes under it.
5 To remove a heat treatment or follow-on process from a routing, right-click on the process node and select Exclude or Let aPriori Decide from the popup menu.
