## Short answer

How forge shops schedule presses, furnaces and heat treat: die change sequencing, billet availability, batch loads, and where finite scheduling pays off.

**Intro:** Forging press and furnace scheduling means sequencing jobs across presses or hammers, heaters, heat treat furnaces and outside processors while respecting die changes, billet availability and batch loads. The constraint moves: sometimes it is the press, sometimes heat treat, sometimes a die that is out for repair. Most forge shops schedule on a whiteboard or spreadsheet because the rules are hard to express in standard job-shop software. This guide lists the real constraints and where finite scheduling is worth the effort.

**Sections:**

#### The Constraints That Make Forging Different

**Body:** A press is not a machine you simply load with the next job. Die changes can take hours, dies must be preheated before use, and some part families can share die holders while others cannot. Billet supply depends on bar arriving and being cut, with mill lead times that can stretch for specialty alloys. Heating equipment limits throughput: a gas furnace takes time to reach temperature and wastes fuel if left idle, while an induction heater changes size with bar diameter. Heat treat is often a batch process on a different schedule altogether, with outside processors adding days. A schedule that ignores any of these looks fine on paper and fails on Monday.

**Bullets:**

- Die change time and preheat before the first piece
- Billet availability, cutting and weighing steps
- Heater or furnace readiness and fuel cost of idle time
- Heat treat batch timing and outside processor lead time

#### Sequencing to Minimize Changeovers

**Body:** Grouping jobs by die family, bar diameter and alloy reduces changeovers and furnace adjustments. The trade-off is due-date risk: grouping too aggressively delays a rush job. A good sequence weighs the cost of a die change against the cost of a late shipment. For example, running two lots of the same part back to back on the same die can save a changeover, while splitting a long run across weeks to ship partial quantities may cost more than it earns. Alloy sequencing matters too, since moving from carbon steel to stainless or titanium may require cleaning, different lubricants or different temperature profiles.

**Bullets:**

- Group by die family, bar size and alloy
- Protect rush jobs with explicit priority rules
- Sequence alloys to limit cross-contamination and cleaning

#### Scheduling Heat Treat as a Batch Bottleneck

**Body:** Heat treat often becomes the real bottleneck because loads are batched and cycle times are long. Building a load means combining forgings that share the same cycle, material and test requirements, and respecting the furnace size and any pyrometry or load thermocouple rules the specification requires. Waiting to fill a furnace delays shipping, while running a partial load wastes capacity. Outside heat treat adds transit and queue time, so the due date for the forging operation upstream should be set from the heat treat date backward. Schedule backwards from ship date through each stage, and track the real time each stage takes to improve lead time estimates.

#### Finite Scheduling in the ERP You Already Have

**Body:** Many ERPs offer infinite or simple finite scheduling that treats a press as a work center with fixed hours per day. That is a start but ignores die changes and batch rules. Advanced planning and scheduling modules can model setup dependencies, but they require clean data: accurate run rates, changeover matrices, and reliable routing. For a shop with a few presses and clear bottlenecks, a spreadsheet-based schedule maintained daily by a scheduler who knows the shop may outperform a poorly configured APS. Invest in APS only when volume and variety exceed what one person can juggle.

**Bullets:**

- Model presses and heat treat as separate constrained resources
- Capture real run rates and changeover times
- Reschedule daily from actual shop-floor status

#### Where AI Fits in Scheduling

**Body:** AI does not replace the scheduler, but it can answer the questions that consume their morning: which jobs are at risk of missing ship date, which are waiting on billets, which dies are due for repair, and what changed since yesterday. A read-only assistant over the ERP can compile that with the supporting records. It can also compare planned against actual cycle times by part family to improve the numbers the schedule depends on. If your scheduling problem is simply one overloaded press, more data will not help; capacity will.

**Cta:** Netray can build a read-only view of late jobs, billet shortages and die status from your ERP so the scheduler starts the day with facts.

**Faq:**

#### How do you schedule a forging press?

**Answer:** Group jobs by die family and material, account for die change and preheat time, confirm billets are cut and weighed, and schedule backward from heat treat and ship dates. Review daily against actual progress because press breakdowns and die repairs shift the plan.

#### Is heat treat the bottleneck in forging?

**Answer:** Often, especially when batch cycles are long or processing is outsourced. Check queue time before each stage; the stage with the longest queue is your constraint, even if the press looks busiest.

#### Do forge shops need APS software?

**Answer:** Only when job mix and volume exceed what a scheduler can manage manually. APS requires accurate run rates and changeover data, so shops with poor data capture often do better improving that first.
