Practice - 5 Tasks

1fill in blank

easy

Complete the code to calculate the chip load per tooth.

CNC Programming

chip_load = feed_rate / (spindle_speed * [1])

💡 Hint

Common Mistakes

Using tool diameter instead of number of teeth.

Dividing by feed rate again.

Confusing spindle speed with feed rate.

The chip load per tooth is calculated by dividing the feed rate by the product of spindle speed and the number of teeth on the tool.

Complete the code to calculate the material removal rate (MRR).

CNC Programming

MRR = [1] * cutting_depth * width_of_cut

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using spindle speed instead of feed rate.

Using chip load instead of feed rate.

Multiplying by number of teeth incorrectly.

Material removal rate is the product of feed rate, cutting depth, and width of cut.

hard

Fix the error in the code to correctly calculate feed rate from chip load.

CNC Programming

feed_rate = spindle_speed * [1] * number_of_teeth

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using cutting depth or width of cut instead of chip load.

Assigning feed rate to itself.

Confusing chip load with feed rate.

Feed rate is calculated by multiplying spindle speed, chip load, and number of teeth.

4fill in blank

hard

Fill both blanks to calculate MRR using feed rate and cutting parameters.

CNC Programming

MRR = [1] * [2] * width_of_cut

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using chip load or spindle speed instead of feed rate.

Mixing up cutting depth and width of cut.

Leaving blanks empty or reversed.

Material removal rate is feed rate times cutting depth times width of cut.

5fill in blank

hard

Fill all three blanks to calculate feed rate from spindle speed, chip load, and number of teeth.

CNC Programming

feed_rate = [1] * [2] * [3]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Including cutting depth in feed rate calculation.

Mixing order of multiplication.

Using chip load incorrectly.

Feed rate is spindle speed multiplied by chip load and number of teeth.
