The hidden cost of manual CAM programming
In most hydraulic manifold shops, programming a manifold for CNC production takes between two and four hours per part. This seems like a fixed cost of doing business and it has been, for decades.
But it compounds. A shop running ten manifolds a week is spending 20 to 40 hours a week on programming alone. That’s a full-time job, often filled by one of your most experienced people - someone who also needs to be on the floor overseeing production.
Beyond the direct labor cost, there’s the machine cost. A CNC machining center is a significant capital investment. Every hour it waits for a program to finish is an hour it isn’t generating revenue. If your programming takes until Thursday afternoon and the machine is ready Tuesday morning, that gap is real money.
The knowledge problem no one budgets for
There’s a less visible risk that compounds over time.
The knowledge of how to machine a manifold, which sequences to use, how to handle specific cavity types, what pilot drills are required before large bores, how crossing holes need to be sequenced to prevent drill deflection lives in people, not systems. Usually one or two people.
When that person is sick, programming slows. When they leave, you face a choice between months of re-learning or hiring someone equally experienced at a premium. Neither is a good answer.
This isn’t criticism of the people but it’s a structural vulnerability in how knowledge is stored.
What HydroCam changes
HydroCam is CNC programming software built specifically for hydraulic manifolds. It works in tandem with HydroMan, PARO Software’s manifold design tool, reading the full feature definition of every hole and cavity in the design. There’s no manual hole selection. No feature recognition to verify. No converting geometry into intent.
The core of HydroCam is the sequence library, a set of reusable machining recipes your team builds once and reuses forever. Each sequence captures how a specific type of hole or cavity should be machined: what tools, in what order, at what feeds and speeds, for what materials. Once built, every manifold that contains that cavity type can be programmed using that recipe automatically.
When you load a new manifold, HydroCam matches every hole to a sequence, assembles an optimized program that minimizes tool changes, handles fixturing for 3-axis or 4-axis machines, and generates ready-to-run G-code.
The result: programming that used to take hours now takes minutes.
The library as a business asset
The sequence library is not just a time-saver. Over time, it becomes one of your most valuable operational assets.
It captures the machining knowledge of your best operators in a structured, reusable form. New hires start from a proven library, not from zero. If your top programmer leaves, the library remains. Standardized programs mean consistent quality across operators and shifts.
The library is built around your machines, your tooling, and your materials, ensuring it reflects your specific competitive capabilities. No two shops will have identical libraries, and yours will reflect what makes you good.
Who this Is for
HydroCam is the right fit for hydraulic manifold shops that:
· Currently use general-purpose CAM software and spend hours per manifold on programming
· Want faster time-to-production without hiring more programmers
· Have experienced machinists whose knowledge isn’t yet captured in any system
· Run 3-axis or 4-axis CNC machines and want programs that account for proper fixturing and hole sequencing
· Need to stay competitive on turnaround time as customer expectations shorten
The setup requires investment and building a comprehensive library is work that takes time and expertise. PARO Software supports this process directly, working with your team to build out the initial library in a way that reflects your machining practices.
After that, the bottleneck is gone. If you want to learn more please visit our product page or watch this video.
