Abstract

One variation of a method includes: receiving a request for a machining strategy for machining a part defining a set of features at a machining facility; accessing a set of characteristics of a feature in the set of features; retrieving a strategy-generating model configured to output recommended machining strategies for machining features based on feature characteristics; deriving a set of recommended machining strategies for machining the feature based on the set of characteristics and the strategy-generating model, each machining strategy defining a sequence of operations and a set of operation parameters for each operation in the sequence of operations; for each machining strategy, deriving a rationale, in a set of rationale, for selection of the machining strategy based on a set of strategy metrics; and presenting the set of recommended machining strategies and the set of rationale, to a user associated with the machining facility.

A method comprising:

during an initial time period:
accessing a corpus of machining data representing combinations of a host of features and machining strategies for machining the host of features;
and
training a strategy-generating model on the corpus of machining data to generate recommended machining strategies for machining a population of features based on feature characteristics of features in the host of features;
and
during a first time period succeeding the initial time period:
receiving a request for a machining strategy for machining a part defining a set of features;
for a first feature, in the set of features, accessing a first set of feature characteristics defined for the first feature;
representing the first set of feature characteristics in a first feature container associated with the first feature;
based on the first feature container and the strategy-generating model:
generating a set of recommended machining strategies for machining the first feature, each recommended machining strategy, in the set of recommended machining strategies, defining a sequence of machining operations and a set of operation parameters for each machining operation in the sequence of machining operations;
and
