CPC software
Every feature a composite cure depends on.
CPC combines equipment control, cure recipes, pre-run integrity checks, complete data records, and automatic quality analysis in one system, refined over decades with the aerospace companies that use it.
Before the run
Load setup, parts, and security
Part entry
Operators enter parts from scratch, from the part database, or by barcode, then assign thermocouples, vacuum sources, and probes on a color-coded attachment form.
Parts on tools
Enter the tool once and add each part as a part-on-tool, inheriting the tool's attachments. There is no limit to parts per cure.
Pre-batching
Enter the next load while the current run is in progress, then make it current with one click to cut door-open time.
Part database
Selecting a part can select its recipe automatically, with checks that every part in the load can cure on the same recipe.
Security
Users and groups get configurable access to screens and functions, with automatic lockout and every login recorded.
Custom screens
Main, sensor, trend, P&ID, batch, run, recipe, and maintenance screens are all configured to your equipment and process.
During the run
Recipes and part temperature control
Direct equipment control
CPC drives every valve, motor, and actuator and reads every sensor directly, with PLC-style logic in ASC's own scripting language and multiple PID loops.
Recipes and segments
Recipes ramp temperature, pressure, and multiple vacuum headers segment by segment, and switch modes, motors, pumps, and alarms as the cure progresses.
Watch groups
Segments end when watched sensor values reach their targets, combined with AND and OR logic, instead of on a fixed timer.
Cascade part control
Air temperature is driven a set amount above the parts to bring them to temperature, controlling on the high, low, average, or median part TC.
Gradient and rate control
Real-time limits on part and load thermal gradients, and closed-loop rate control that corrects for exotherms and pressurization.
Vacuum line control
Each line can be set to vacuum, off, or vent, and a leaking part can be vented or isolated automatically based on its probe.
Integrity checks
Five checks before every cure
Developed with The Boeing Company over many years, CPC's integrity checks must all pass before an automatic cure can start.
Field check
Validates the part entry fields: no blanks, no duplicate serial numbers, and the right number of characters.
Sensor check
Confirms every attached thermocouple and vacuum probe reads within its tolerance band.
Header check
Proves each vacuum header can be controlled to set levels with the required stability.
Drawdown check
Catches loading errors, such as an unconnected or mismatched vacuum line, before they ruin a part.
Leak check
Closes the vacuum sources, waits, and fails any part that leaks more than the allowed amount.
Saved reports
Each check produces its own report, printable before the run and saved in the run's datafile.
After the run
Data, reports, and quality
Complete run datafiles
Every run saves part and attachment information, the full recipe, integrity reports, alarms, and interval sensor data in one file.
Run database
Search runs, parts, and alarms across one CPC system or many. Data can also be parsed to a remote SQL or ODBC database.
Reporting and analysis
Numeric, trend, alarm, and recipe views with zoom and statistics, export to Excel, and batch, numeric, trend, message, and quality reports.
Automatic quality analysis
Quality cards check air and part temperature, rates, pressure, vacuum, and soak times phase by phase against your specification.
Calibration
Step-by-step linear and multi-point calibration of thermocouples, RTDs, and transducers, with printable reports.
Certification
Check and record sensor readings at defined levels with tolerance checking, producing a concise certification report.
Up-time and access
Redundancy and remote operation
Dual-PC redundancy
In a Level II system, PC-B backs up every configuration and run in real time and takes over control if PC-A fails.
PLC redundancy
Redundant PLC processors and communication links, or a duplicate PLC rack for smaller equipment.
Client-server
CPC-Server runs the equipment and CPC-Client runs the screens, so control rooms, maintenance, quality, and clean rooms can all connect.
Web and cloud access
Optional secure web access on your network, and a cloud version for remote monitoring, reports, cure programming, and data analysis.
Email and text alerts
Optional email and SMS messages with process data, alarms, and run status, including replies to emailed requests.
No chart recorders needed
With dual-PC redundancy, standalone setpoint controllers and paper recorders are unnecessary, though we can quote them.
