First Part Runs

Every Haas machine includes the warm-up program. Use this program if the spindle was not in operation for more than (4) days or you are about to operate the spindle at a high speed without slowly increasing the speed first.

•  Note: You can make a program that operates the spindle warm-up program after a sleep mode program M95. Refer to the manual for M95 operation.

• It is recommended you put a tool holder in the spindle for the spindle warm-up program.

For 10,000-RPM spindles and above, you must always use a balanced grade tool (balanced grade is G2.5 or better ANSI S2.19) in the spindle when running the warm-up program.

A graphics run is a digital test run / visual simulation of the G-code program on a computer screen/control panel. This allows the operator to see a 3D representation of the part being machined and how the tool path will be executed, without the machine physically moving. Graphics runs can be used to check for potential problems such as tool collisions, over-travel, and other issues that could cause damage to the machine or the part. The operator can make any necessary adjustments to the program before running it on the machine, reducing the risk of errors and increasing efficiency.

• The primary benefit of a Graphics Run is to test your program's G-Code for machine alarms/errors due to code and/or setup.

A dry run is a physical test run of the G-code program on the CNC machine, but without the cutting tool engaged in the material. In a dry run, the machine will move through the program's tool path as if it were cutting, but without actually making any cuts. This allows the operator to test the program for potential problems, such as incorrect tool paths, improper feed rates, or other issues that could cause damage to the machine or the part. A dry run can help to reduce the risk of errors and increase efficiency, as any issues can be addressed before actual cutting begins.

• To perform a Dry-Run on a Haas machine, you can apply temporary, additional offsets to raise either the Tool Height Offsets (NOT recommended) or the Work Z Offset (Recommended) high enough that the tools will no longer contact the part

  • Example: If G54 Z0 is at top of part and tools go no lower than 2" below G54 Z0, then add 2" pus clearance to the G54 Z offset value, to have the program run 2+ inches above the part

  • This tells the machine that the program is actually above where the part really is, and therefore the tools will perform the same X & Y movements, just hovering up above the part and "cut air"
