How to Hire a CNC Programmer in 2026

Q: First-article on a Fanuc mill. G54 Z0 was touched on the vise bed, not the 32 mm part top. Geometry H01 is 118.4 mm. Dry-run is off. The first motion after M03 is G43 H01 Z2. then G01 Z-8 F180. Cycle start is 30 seconds away. What do you do?

Correct answer: Reset before cycle start. Re-touch G54 Z0 on the actual part top, leave H01 at 118.4 mm if that length is true, then graphics and single-block the G43 Z2 move. d is correct: table-based G54 Z0 means programmed Z2 is 2 mm above the table, about 30 mm into a 32 mm part, so you abort and re-set the work Z. a fails because H01 is tool length from gage line to tip, not a 118.4 mm air gap above the table. b fails because mixing a WCS error into H wear corrupts every later Z and is not a 30-second first-article method. c fails because G92 stacked on a wrong G54 is a second floating origin and is easy to leave in the program.

Q: On Fanuc milling cutter compensation, how do G41/G42 geometry (radius) and wear differ?

Correct answer: G41/G42 offset the path by the D register. Geometry is the nominal radius; wear is a signed trim. They add. Wear is for tenths of a millimetre of wall size, not a substitute for posting the correct tool diameter. c is correct: Fanuc adds D geometry and D wear and offsets left (G41) or right (G42) of the programmed path. a fails because wear is not a work-offset write. b fails because G41/G42 are side-of-path, not climb/rapid. d fails because D00 is typically a zero offset, so G41 does nothing and walls come out oversize by about one radius.

Q: 4th-axis mill. G54 X/Y/Z were set at A0. The CAM program assumes the part is already at A90. First motion is G00 X-80 Y0 Z50. What is the risk and the rule?

Correct answer: At A0, programmed X-80 is in the unrotated frame and can rapid into the trunnion or clamp. Index A to 90 at a known Z clearance first, then approach XY. Do not rapid XYZ as if A were already 90. b is correct: work XYZ at A0 are not the CAM A90 frame; the first rapid is the crash. a fails because Z50 does not make a wrong XY vector miss the fixture. c fails because A is a real axis and G54 may include an A origin. d fails because combining an index with X-80 is still an undefined, usually unsafe, simultaneous move.

Q: How do you prioritize competing tasks when multiple deadlines occur simultaneously in CNC Programming?

Why it matters: Evaluates time management and prioritization under pressure. What to listen for: Green flags: Uses structured task lists, clarifies urgency with supervisors, and communicates transparently.

Q: Describe a time when you revamped an inefficient workflow in CNC Programming. What was the measurable impact?

Why it matters: Evaluates continuous improvement and data-driven results. What to listen for: Green flags: Identifies root cause, involves stakeholders, implements measurable KPIs, and tracks ROI.

Q: How do you formulate a multi-year operational strategy in CNC Programming that balances short-term profitability with long-term resilience?

Why it matters: Evaluates strategic foresight and executive acumen. What to listen for: Green flags: Aligns with market trends, incorporates scenario modeling, manages financial risk, and establishes clear milestones.

Q: On a Fanuc mill, what is the difference between G90 and G91?

Correct answer: G90 treats XYZ as positions from the active work zero. G91 treats XYZ as distances from the current tool position. A leftover G91 after a shift is a common crash. b is correct: G90 is absolute in the active WCS and G91 is incremental from the current position; mixing them without an explicit cancel is how pockets walk into clamps. a fails because neither code selects machine coordinates (G53 does) and neither sets feed units (G94/G95). c fails because the identities are reversed and Fanuc mills typically default to G90. d fails because mills use G90 for hole patterns and contouring as a normal standard.

Q: A G02 R-word arc alarms with a 0.3 mm start/end radius mismatch. CAM shows a 12 mm radius corner. What is the right fix?

Correct answer: The control compares start-to-center and end-to-center radii; 0.3 mm exceeds the parameter. Fix endpoints in CAM or post I/J from one center. Do not open the radius-error parameter to 0.5 mm just to run. a is correct: Fanuc radius check fails when start and end do not lie on one circle within the parameter, often from CAM rounding. b fails because G10 does not license a geometrically impossible arc. c fails because feed does not change the radius math. d fails because G00 drops the corner and can gouge or leave a step.

Q: G84 tapping 12 holes. The tap snapped in hole 7. The cycle has no tool-break skip. The broken shank is still in the hole. What do you do now?

Correct answer: Feed-hold/reset. Do not continue G84. Retract, kill spindle, quarantine the part, extract or EDM the tap, then a programmed skip/probe before the next hole. Do not 'hero tap' hole 7 by hand in the machine. d is correct: a broken tap in the hole makes the next G84 a second wreck, and extraction is not a live cycle. a fails because hole 8 is not the only risk and hole 7 is scrap-in-progress. b fails because a shallower Z still collides with the stub. c fails because starting a new tap on a broken one in the same hole destroys the hole and the holder.

Q: Describe a situation where you had to handle an unhappy client or difficult colleague.

Why it matters: Evaluates emotional intelligence and professional de-escalation. What to listen for: Green flags: Listens actively, shows empathy, focuses on problem resolution, and follows SOPs.

Verified Domain Questions (Junior Tier)

5 verified Easy domain evaluation questions extracted directly from the SkillSauce question bank.

First-article on a Fanuc mill. G54 Z0 was touched on the vise bed, not the 32 mm part top. Geometry H01 is 118.4 mm. Dry-run is off. The first motion after M03 is G43 H01 Z2. then G01 Z-8 F180. Cycle start is 30 seconds away. What do you do?

Easy

aCycle start. H01 of 118.4 mm keeps the tip 118.4 mm above the table, so Z2 is safe.
bIn the next 30 s, subtract 32 mm from H01 wear so the table-based Z0 'becomes' part-top Z0.
cLeave G54 as-is and insert G92 Z32 on the first line as a field patch, then run.
dReset before cycle start. Re-touch G54 Z0 on the actual part top, leave H01 at 118.4 mm if that length is true, then graphics and single-block the G43 Z2 move.Correct

Explanation: d is correct: table-based G54 Z0 means programmed Z2 is 2 mm above the table, about 30 mm into a 32 mm part, so you abort and re-set the work Z. a fails because H01 is tool length from gage line to tip, not a 118.4 mm air gap above the table. b fails because mixing a WCS error into H wear corrupts every later Z and is not a 30-second first-article method. c fails because G92 stacked on a wrong G54 is a second floating origin and is easy to leave in the program.
