Machine, tools, and stock
Describe the physical setup your job will use.
The drawing describes the part. Your machine, tools, and stock describe how that part will be made. Confirm these records against the actual equipment and material before calculating a job.
Machine and post-processor
The post-processor writes output for the selected controller. Choose one that matches your machine's requirements.
A machine record can also describe travel limits, safe height, feed limits, spindle control, and tool-changing capabilities. Missing limits reduce what Upcut can verify; an unknown envelope is not an unlimited envelope.
Tools
Select the actual cutter you intend to install. Its geometry, tool number, feed, plunge rate, spindle speed, and stepdown affect the job.
Operations reference a tool rather than requiring those values to be re-entered everywhere. Review the resulting values for the selected material and setup; do not assume a catalog entry is suitable for every machine or workholding arrangement.
Stock and material
Check the stock's width, height, and thickness. Confirm that the selected material matches what will be loaded on the machine.
Material settings can scale cutting values. Review the effective values shown for the job, not only the original tool defaults.
Physical setup still matters
Simulation cannot establish that the real cutter, clamps, stock, and origin match the project. Confirm those on the machine using its operating procedure before running exported output.
