Hybrid additive and subtractive manufacturing system and methods of operation

A method of coordinating additive and subtractive operations in a hybrid manufacturing system, the method comprising:

• receiving an additive data set specifying additive regions where at least one material should be additively deposited by an additive toolhead;
• receiving a subtractive data set specifying subtractive regions where at least a portion of the additively deposited material should be subtractively removed by a subtractive toolhead;
• adding the additive data set to a spatial-temporal map, wherein the spatial-temporal map includes map regions, wherein at least some of the map regions include additive time intervals indicating when additive material deposition within the region is complete;
• identifying a subset of the map regions overlapping in space the subtractive regions of the subtractive data set;
• scheduling the subtractive regions based at least in part on the additive time intervals of their respective map regions;
• and
• generating a combined sequence of additive and subtractive operations from the spatial-temporal map.
